Yup, it's a gambler perspective in terms of controlling their participation knowing that gambling is more on risk and without good control you'll find yourself empty-handed to the point that it will ruined your finances, though, like you mentioned there are some who manage being lucky and change the direction of thier lifestyle but ain't that many compared from those who loses their finances and turned to poverty because of being out of control with the money that they spent for gambling.
We've all been saying almost the same thing. Having control over your spending is a pivotal way to manage your money effectively, not in gambling alone but in life generally. People who have more discipline to their account, then to save more money for the next day.
Sometimes I used to wonder why people end up spending all their hard earned money in gambling without thinking of the repercussions then I answer my question by thinking gambling as a thing of pleasure since it's mostly a fun game and humans beings can spend all they have to satisfy their urge or pleasure.
Since gambling comes with this addiction, it also makes it easier for people to fall into that trap of spending their money in gambling. So, with this thoughr, it makes me feel like whether one's gambling for money or fun, the possibility of them spending their hard earned money just to satisfy their pleasure will always make them to make such mistakes.
In response to what OP highlighted, gambling in itself doesn't bring about poverty as some people have made their fortunes through gambling but because of this urge to satisfy one's pleasure while spending money, they end up exhausting all they have in gambling.
