There are so many success stories around us when people make big money with gambling because they are lucky and get huge profit by betting on some event and casino.
Also this one. If people see a person win big at gambling, he/she will get inspired and think that he/she might be the next big winner of the game (which is false). The thing is that instead of making it big in profits, an addict gambler would likely make it big in debts.
Yes that is i think so this one of the big reason so many people try their luck to get inspired by other great winning but i think everyone want to get some free money using their luck with hope they will win and get back all losing with profit so they keep continue gambling.
