I think this is true and why programs like like Pluribus, Libratus and DeepStack have outperformed professionals in both heads-up and multiplayer no-limit Texas Hold'em. It's not reading social cues like traditional players, but just relying on probability. Even when giving perfect knowledge of the computer strategy to humans, they're still unable to exploit.

Humans are improving their game by using solvers and introducing randomness into their decisions. For instance, an optimal strategy given a hand might be "fold 80% of the time". One way to do that in live play is look at the second hand of a watch and fold unless it seconds (in this case) are about 48 (80% prob).
