After almost a hundred hands, I would have expected that each player's chip stack at the end of the night would be just as likely to be odd as even. Instead, almost always, zero or two players have odd stacks.
We play with an buy-in stack of 40 chips per player. A player who runs out of chips buys chips from another player who has plenty. Individual bets are up to five chips. No blinds, but dealer antes a number of chips equal to the number of players.
