Exactly, someone who is already addicted will only be able to stop when they really run out of all their money at that time, someone who is already addicted has a very high level of curiosity so that is what makes them always act excessively in their gambling activities, not only that, they also put hope in winning and this hope is the reason why they act excessively such as doing more experiments to be able to multiply the money they carry. On the other hand I understand that they can win but unfortunately people who are addicted cannot make wise decisions when they are in a winning situation and obviously at that time the decision they make is to apply greed to get something much bigger which basically cannot be sure whether it will be able to come true or not more than just a hallucination in the mind.

Addiction is a very bad situation in gambling, losing is a sure thing and even if you manage to get a win but I would say that it is not a real win for you because when you are addicted then you will never feel enough / satisfied with what you get which in the end ends up losing everything. Therefore, from the beginning we are advised to have a good approach to gambling, having self-control along with limits in gambling will make it easy to stop under any circumstances, especially when losing.
