The issue is that having "the fundamentals" is not enough. Jinbe is able to outperform Fish-Man Karate masters who are
superior in technique to
others with dozens of degrees of
black belt mastery, calling their skill that of a novice, so even if Sarada is able to discern it basics, that doesn't guarantee her a chance to exploit his usage.
This literally does not matter in the eyes of the Sharingan. Like, she'll instantly be able to copy the abilities and techniques of the fighting style off of a glance and would be capable of using it as long as it's biologically possible for her. As soon as she takes a look at Jinbe's usage of it she'll be able to discern how he uses it and how to exploit it thanks to the Sharingan's ability to read people's movements before they actually use them. Your scans here don't address any of that.
Ace was only able to do this because he had
superior AP than Jinbe with explosive attacks and stronger Haki. Sarada has neither of those. Fish-Man Karate has been noted as a
direct counter to fire-based attacks on several occasions (
his Murasame literally KO'd a walking Fireball Jutsu) and because he also has higher AP the attacks would simply
overpower and destroy Sarada's.
I'm specifically referring to countering Jinbe's Fish-Man Jujutsu, not his Karate. Like his actual ranged water attacks, Sarada should be able to counter just like Ace did in that scan I sent before. Their AP difference is negligible here.
IK Jinbe's Karate will disperse Sarada's Fireball Jutsu, it's why her Ninjutsu was never her wincon here.
I still don't really consider this as impressive as Jinbe. Being able to skillstomp dudes who are more technical than 40 to 100th degree masters as well as outmatching folks on the level of Rob Lucci (the most skilled fighter in the history of a 800 year organization of martial artists) in my eyes firmly places Jinbe above Sarada in skill. If the fight gets close, because of his skill, experience, and superior LS the gap would just seem wider. I'm not saying that Sarada isn't skilled but it's very obvious who is superior and it isn't close enough to where fighting cqc won't put her at a disadvantage.
Heavily disagree and I think you're underestimating her skill and the skill of Naruto ninjas in general. A reminder that just like Lucci, these ninjas are formally, battle and even war tested ninjas who've been trained and been fighting since they were like 8 years old? Most adults by the time of Sarada's era had already seen at least one war and even older ninjas were conscripted into war as kids (such as Kakashi for example), Sarada fighting and being comparable to Ao who was able to survive two different Ninja World Wars and survive an encounter from the likes of Shisui Uchiha who was hailed as a genius among the Uchiha, which is incredibly high praise considering the value the Uchiha have within the village as one of the greatest clans in all of Konoha. This is the same Shisui who trained constantly with a young Itachi (said Itachi went on to be an Anbu at only age 11) and became a Jonin only 4 years after being a shinobi, and even fought Danzo and his men, who are no slouches either. Sarada and her team fought off this Ao and beat him.
Sasuke praising Sarada being better than him, this being the same Sasuke that Orochimaru, one of the great Sannin looked at and saw massive potential in and took him under his wing so that he could eventually take his body and his Sharingan, Sasuke said SARADA was better than him. And I've already mentioned her training with Sakura and how that relates to Tsunade. 2/3 Sannin Sarada has gotten indirect accolades from. These are all master ninjas who have numerous of achievements and have fought in many wars. Experience hardly means much in this match because not only has Sarada at the age of 12 spent pretty much her whole career fighting people who have much more experience than she does (Buntan, Shojoji, Ao, Deepa) but she's also trained with many adults who've given her numerous of credit for how skilled and intelligent she is for her age (Shino, Konohamaru, Moegi, Sasuke, Sakura). Not to mention that the Sharingan is highkey a cheat code that allows her to rapidly close the "gap" in skill or experience due to how much it accumulates in a glance. She's essentially learning at an incredibly fast pace as she fights Jinbe, and as the fight continues the more she'll learn and understand his fighting style, strengths and weaknesses.
Instinctive Reaction that allows them to fight without connection to the rest of their senses.
Sure, while he would be able to fight without his senses, his senses will still be overwhelmed by whatever imagery she decides to cast upon him.
She can cast many mental images like him getting stabbed or him getting killed or paralyzed or even read his mind and then cast a triggering memory that'll cause him to waver. There's a multitude of Genjutsus she has access to that Jinbe has no answers to. So while he can be able to move his body, he'll struggle to perform at full capacity while his mind is being overstimulated.
