I think that gambling is what all players come to. Someone starts playing immediately for money and only for it, such a gambler calculates the odds, looks for the lowest commissions and the best conditions for depositing and withdrawing funds.
And someone comes for fun, I think these are those who came to an online casino out of boredom or got free spins. Such people do not expect profit from the casino, they have fun learning this pleasant unknown.
But as soon as they win... the thirst for profit will come to them.
