In this regard the most important thing is greed. When a gambler gets too greedy he will keep losing. Excessive greed usually increases the risk. If any one can win the game again and again but lose it all at the end. That's why you have to deal with greed. Addiction and greed are two different things. If a gambler can control his greediness, he will be able to control his addiction.
Greed will prevent a player from losing a lot, since a greedy one will always bet low, which in the end will not allow him to lose a large amount. And just as the greedy just can not part with their savings, it is embedded in their brains, watch the film "Radin" by Fred Cavaye, a clear example of how a greedy person saves on literally everything. ) I doubt very much that people like the protagonist of this film can be addicted to gambling. Addiction and greed are completely different things...
