The chances of being able to stop gambling can indeed be said to be very slim, especially if they are already heavily addicted, of course it will be difficult to get rid of the addiction that has been attached and ingrained. Not to mention those who cannot accept advice from other people, friends or family, they can even rebel when advised because their brains have been quasi by gambling so they cannot accept when advised, the main key is in themselves. if they are sure and consistent to stop gambling maybe they can do it, but on the contrary, if they do it without really doing it, it will only be a waste of time.
It's true what you said. People who are already heavily addicted will do anything when they have run out of capital to gamble, even if it is at great risk to them, as you said committing crimes such as stealing or others which essentially with great risk, of course this is clearly endangering themselves. and in the end they will be confused themselves.
stopping a gambling addiction is indeed a difficult thing when an addict still has a budget for gambling and if it is possible that he runs out of budget he still has a way to continue to indulge in the desire to gamble and what I know is that a gambling addict will be able to stop if God reminds him.
I mean a compulsive gambler who finds it difficult to accept advice from other people, they will only become aware and have the desire to stop gambling when they no longer have anything, even they have lost their house, etc. as if they have become addicted and at that time the addict will feel sorry for their actions and want to recover from their addiction.
but all of that still depends on one own commitment because there are many people who have lost whatever they had by gambling and trying to steal, being caught by the police and in prison. after leaving prison, they are still gambling, which means that commitment is very important.
