It's not that they do not want help it's just that they are in total denial that they are very much addicted to gambling, they do not know who to approach and what are the stps to be take to get out of that prison, only a proffesional can do that for them.
Maybe not in total denial since you are talking about grown-up people. They are perhaps deflecting on the subject and just thinking about themselves, whether it is true or not. Maybe the professionals could help you in some way, but you could never be sure until you help yourself. That's the real breakthrough if you think about it.
Lolzzz, there are people who have already made up their mind to be useless for the rest of their life.

How are poor people even allowed in that betting store? Are you sure they are poor or just that they put every money in gambling? Because definitely, people in the slums could not afford to gamble. And telling someone that they are useless is not a proper term. Maybe it's a matter of self-discipline, and they need to be educated with what they are experiencing.
