No, reread Jinbei's explanation. Fishman Karate basically manipulates water to send shockwaves in the body; humans contains water, atmosphere contains water, cells contains water, basically everything that contains Water, in short, Bang cannot dodge Jinbei's fishman karate because he consists of 70% Water. Fishman karate can be used on dry land and underwater (as long as Jinbei is fighting in an environment that contains a tiny bit of water, he cannot use it in space for example). Also Jinbei can use fishman karate to not only manipulate bodies of water but also the liquid inside bodies, which ignores durability to a extent and can cause internal damage.
That's why Luffy, nor anyone on-screen could ever dodge Jinbei's fishman karate, despite having precognition on their side.
