This is a confusing misinterpretation of the parent comment. He isn't saying it isn't easy to count cards, rather that there isn't a widely seen public method to do it in 2020, and that there isn't math to prove it is profitable with casinos targeting advantaged players.

Asking to prove it is like asking to prove that tic-tac-toe is a solved game, since its trivial to understand how it works
