Lack of money alone is not the only reason why gamblers get addicted, because I have seen people who has money and yet still struggling with gambling addiction, but rather what I think is the root problem is self control and contentment. Because until a gambler can have self control over his urge of wanting to satisfy his immediate gratification, and the urge of wanting to chase after loses even after playing for quite a long time and you noticed you have little or no chance of winning against the casino. So until each gambler is able to write them that thing that makes gambling irresistible for him, and makes a clear plan on how to resolve it, gambling addiction will still remain a major challenge in the gambling community.
I am also of the opinion that prior orientation about gambling is another thing most gamblers are lacking today. Majority of the gamblers out there did not really get orientation on how gambling works before they started it. Some just started it out of frustration in desperation to make profits, some do that while seeing it as a career or job to earn a living while some just do it for fun so the approach varies and this is what builds players mindset towards why they gamble and they don't have a broader perspective about gambling as they never got the orientation before they ventured into it hence you see players easily get addicted and can not control their gambling urge because there was no foundation to guide them before they became gamblers.
Also, orientation can also give a gambler idea on how to plan their gambling lifestyle and schedule, teaching them to also have a budget for their gambling. Training them to stick to their gambling time and remain disciplined irrespective of whatever happened be it a winning or losing streak. Lastly, it also inform a gambler on how to play with funds they could afford to lose without going bankrupt or borrowing to gamble.
