I think p2p here means person-to-person games where players play against each other and not against the casino
Then it's not P2P, otherwise all multiplayer games (without bot/AI) is qualified as P2P game
What concerns me in such games is how the provably fair algorithm works and how random numbers are generated! Also, how to know you are betting against a real player not a bot created by the casino?
Probably similar with centralized casino where they show hash of seed (before game started) and reveal the seed (after game is done)
