That's exactly the point. If someone cries out for help, then you can possibly guide them if you have solution to their issues but If you don't, then you can refer them to something that can help them. I just don't know why some people doesn't realize it until it's too late.
If it starts with a sincere intention, there must be a way to stop even though the person's involvement has entered the addiction category, but the healing process may take a long time and also requires much more control from those closest to them. Other healing methods can refer to psychological places where people can be more directed to be healed based on their abilities.
In essence, we only need to provide encouragement to addicted people so that they can be more motivated to stop and the rest provide more positive activities so that they don't remember the gambling that they often do.
