I would explain it this way: “Yes, there is a component of chance, but that chance resides in the cards you touch, not in what you do with them. If it were purely a game of chance, everyone would win and lose equally. On the other hand, in the long run, whoever calculates the odds, manages their capital, controls risk, interprets hand ranges and makes better decisions than their opponents, has the advantage. It's like poker: you don't control what cards come out, but you control how you play the cards that touch you.”
