So it basically still boils down to a question of determinism vs, well, not free will but, I guess “indeterminism” would be a word for it. Semantics kind of break down at explaining the nature of existence at some point. I wonder if that is true for mathematics as well.

It’s like that quote of Alfred Korzybski’s, “the map is not the terrain”. The explanation is not reality, it must by necessity be something less, or something different from it.
