When someone is addicted to gambling, we can all say that the person is no longer himself; they are no longer able to control how they place the amount they spend, and when they can call it a stop, when they have gotten to that stage of becoming addicted to the game, they do whatever is necessary just to make sure that they feed their urge to gamble, which is the way most of these rich people run into big debt more than their net worth.
Gambling addiction can lead to poverty in everyone if there is no better control by ourselves. Because this can lead anyone to continue gambling on the pretext of wanting to return the amount of money he or she has previously bet in gambling. Because when someone doesn't win and still has money to bet, that's when he should stop by not prioritizing his desire to continue gambling in order to achieve a win where there is no guarantee at all.
For me, gambling addiction is different from drug addiction and thus, gambling addiction can basically be eliminated if the person is also aware of his/her finances that are getting worse. Because after all, for me it is not about addiction but they are only trying to get back the money that has been lost and thus, they will continue to gamble to get profit to cover all the losses. Thus, they will never succeed so they also become bankrupt because they have spent all their savings or wealth. So yes, in this case basically the person can stop if they realize that there is no chance to catch up on the losses and if they are aware, then of course it will be easy for them to stop gambling before everything is lost.
