of course I ultimately want to win the game so I can get money. I think everyone gambles because of that, the only difference is those who can't control themselves so they become addicted.
Well, that's not the case with everyone. Some gamblers gamble just to pass their time and they don't want to earn money from gambling, and even if they do, they would only want to win so that their bankroll doesn't get over and they can gamble for as long as possible and also have some money left for gambling later because they find it fun and cheerful. Such gamblers don't think of winning a lot of money with a small bankroll or getting rich through gambling, etc.
The reason why a person gets addicted to gambling is that they want to earn money from it and lack self-control, so when they start gambling, they win and then lose, and when they lose, they can't accept that and try to recover the money, and in that process, they lose more, and it continues from that point onwards until they become completely caught up.
