I would imagine in many games randomness (e.g. through throwing dice, or pulling cards from a randomized pack) add noise, but the underlying strategy (including processing data, calculating probabilities etc.) still help. In such a game even though an AI might be superior, the randomness might mean that occasionally the human wins. Or for an extreme example, if nothing you do in the game really matters, it's all just down to random chance, then the AI:human win rate should approach 50%. But such a game would probably not be particularly enjoying to play.

But yes, I think you're right that you'd need a game where crunching a lot of numbers really fast doesn't give you an advantage. For instance, if the state space of the game is so big that number crunching is useless, and other approaches like AI style pattern matching (used IIRC by Alpha-Go?) don't work either.

Though ultimately, what is the uniquely human trait that would allow a human to beat an AI? Can you make a game that depends on that? Is there even such a thing?

I guess all the slot machine players tend to differ in opinion there :)

Sure, slot machine operators adjust winning chances so players keep on playing, but to a player, it's not influenced by anything they do, other than "just one more time and I'll win".
