Well, basically the purpose of gambling is earning money and getting rich, like I know a lot of people who are dreaming to be rich from gambling which it's kind so hard and probably impossible for some people. I mean, the people who will be rich from gambling are the ones who just gamble once and earn big money that will make me rich and then they just stop.
Not actually all people who gamble thinking to earn or getting rich quick there are also many people who gamble just for fun or gamble for a past time.
Gambling is not getting your rich overtime that is why gambling casino is being made it's because it is just for entertainment purposes. People who treat gambling casino as a source of daily income will always end up losing large money because they always continue to bet and greedy even they already win a good amount. It is one of the bad sides if you treat it as a source of income and think to get rich fast.
