Seem pretty consistent with what he's said the entire time in BK. He doesn't care about being the best in the world etc, only wants to be the best version of himself. Kyrie's said the same things.
I guess it can be splitting hairs when wanting to be your best self just also happens to be the best player on the plant, but that's only because of who he is as a player rather than a target he set for himself.
So in other words he's saying "I'm just here to ball to the best of my ability, y'all can take care of the hot takes about who's the best ever." What's wrong with that?
