Learning experience as they say will come to these gamblers that are uncontrollable. And they will only have that when they have no more money to bet for.
But the hard headed once, those that never give up will continue to gamble and will make themselves comfortable and in favor by being positive thinkers.
They'll have an optimistic mindset that everything can be recovered if they continue and will even more winnings if they do so.
You need to control by any means to prevent taking that route to lose more money.
If they are already decided, they cannot control the urge anymore. They'll become more addicted and bound to lose more.
