Either way, 2C has more evidence than just those statements, Mori has been showing much more, he was stated to "achieve a perfect balance between gods, mankind and demons" by the prophecy's own words, which Mujin should've filled but failed as it turns out Mori is the God of the Prophecy:
These could be interpreted as being universes: Gods are the heavenly realm (which is a different space time), Mankind is the universe (different space time) and Oraeguk aka the demons have also been called a "dimension" before, therefore having a different space time than the main universe, Mori being the perfect balance means he is the one who connects these universes, or just rules over them (stated by Xuanzang)
Or him achieving Nirvana, which is the state where you're cut off from the Universe as a whole and all it's concepts, laws. Which has been shown to be true in GOH aswell:
Here, Baek only "thought" he achieved Nirvana but he has studied books and learnt from it how Nirvana works so it shows that the verse follows the same logic on Nirvana (this would only give mori Low-2-C tier but this can be used).
Karma was stated to be an existence that carries all of creation, which is all the different space-times in GOH aswell (This was later confirmed by Xuanzang's statements):
I asked someone on discord (who understands Korean) and they said that these kanji officially (without the shitty translation) means this:
Which means "an existence that carries (or is - this needs more explanation%investigation) all of creation, further proving he is the balance between the worlds and time spaces, essentially meaning Karma is the existence that carries creation.
Just know that I don't wanna like, desperately get mori to 2-C, I just investigated his 2-C scale, and with all this he should be with no effort in the 2-C tier imo.
Edit: We investigated it properly with his korean friend and it means this:
"A being who carries all of creation" with Karma.
