Playing just for fun alone without considering the winnings is a bullshit reason. We are gambling to earn money and that's the source of our entertainment. Controlling the amount of money that used in gambling is just a method for minimizing the emotional damage once players lose but that doesn't mean he is ok when he loss his money. Greediness is what push us to gamble since gambling is the best source for quick profit, There's a lot game available online if we only want to entertain our self. But we choose to risk our money in gambling to win and that's the reality.
That's right, someone will be happy if he gets a win from his bet. Having fun is not enough if the contents of the wallet are all gone, the purpose of someone was playing gambling is only to win, if only for fun there are many other ways that can be done.
Like going to a discotheque with a beautiful woman or feeding a hungry beggar can also make a person feel good because he has done something good.
