First time hearing that syndrome, probably yes they can save themselves if they managed to hit a big win. That kind of effect to gamblers is really worse, imagine instead of living fully in the present, you will keep deferring joy and fulfillment because of your addiction. Probably this kind of behavior can still be saved by going through a professional and also moral support and help from the family members. I think still relying on gambling hoping to win big will just keep things worst.
