This might not be happening to "everyone"; fortunately, a few individuals are probably fortunate enough to achieve a more positive outcome by extending their gambling budget beyond what they initially set. However, for the majority, I assume luck isn't on their side. There are winners, there are losers, and some break even. Moreover, having less control can negatively impact your relationships, including those with your family.

I've never heard of gambling addiction helping to improve mental health, and it certainly never helps meet an "urgent need."
