Having the mindset that gambling is a shortcut to poverty is not bad only if we have a good strategy that will be able to be making money for us. It is not easy for every gambler to be making money from gambling and that's why we ought to bet on games that will give us profits not random games that will give a little profit and game the profits back from us.
People that do not have a job or something doing that will always keep them busy are the ones that will always end up having gambling addiction and other complicated gambling issues.
Maybe the bad thing is having a mindset that gambling is a shortcut to success or wealth, this kind of mindset is what I think many people experience whose lives are ruined by gambling because with this kind of mindset they tend to become someone who is addicted to gambling by ignoring the risk side which is clearly more likely to happen compared to the opportunity to get profit in gambling.
In my opinion, there is no game that will give us a definite advantage if it is gambling, all games called gambling have a greater chance of losing than winning.
