If someone only played and studied with stockfish (or other chess engines), how would their playing style and performance be against human players? Can anything be learned from an engine that can't be from a human?

I know stockfish moves can be hard to understand but I don't think it's beyond any human's grasp to understand the game like stockfish does. Any further knowledge would exclusively come from an engine either through analyzing/playing games or using the analysis board. No human content even if it was heavily influenced by or a commentary on an engine. It could be at any point in their journey that they decide to take this approach, beginner to intermediate to master.

I don't have a lot of knowledge in how chess engines work, so in case any particular chess engine has its flaws, I'd say using several different ones would be fine.

Asking out of curiosity as well as if this could improve someone's chess, even if it might not be the most practical or entertaining approach.
