It's 2022 already, you can almost access anything through internet. So, moving in environment without gamblers won't change you that much. Unless you completely stop yourself from using internet (which is nearly impossible to do) and focus on something profitable. Of course, the amount should be decent or near what you are aiming in gambling so it can satisfy your craving in profit.
so far the gambling place as a user is a place of entertainment and with gambling you can get a lot of money when you receive luck, some people who are technology savvy and often surf the internet, they must have tasted the world of gambling with various models, and it is proven from year to year Gambling sites on the internet have a high demand.
What do you think if in this day and age there is no internet and we are still in the current pandemic, do you think it will be okay with gamblers all over the world? although the person who can gamble in a land based casinos is limited.
The only thing that will make someone to change from it's decision. it's because of lacks of funds but when someone is rich very well which nobody can bend it decision unless it undergoes numbers of advices from prominent people. Because a situation that changes the decisions of someone emotions and conditions is very difficult and especially for those people who have what it takes to control and stamped for their words. But from this your analysis, i have not see were it relate or collabrate with gambling issues.
It's true the only thing that makes a person want to change is his decision and it requires strong determination. I do not agree that lack of funds can eliminate his bad habit of gambling. I think lack of funds is one of cause and effect, it is not impossible that he will do his gambling again another day when he has money. and this is not at the core of the topic of this thread. Likewise, advice from prominent people or clergy does not fully help people who are addicted to gambling.
The change of a person from a gambling addiction always depends on the person who is addicted to gambling, and I agree with you on that point. The real change really comes from oneself first, second only to what they say family or close friend.
