Some are not addicted to the being a winner, they are addicted to the satisfaction they feel when gambling, it doesn't matter whether they win or lose it's just something they can't control. People like this would go to any length to get money just for them to fuel their gambling addiction. Both the rich and poor people might go through this, it's kind of a mental disorder and it takes a lot of discipline to stop
It's hard to in that shoe when every kind of people deals with it. That is true that both rich and poor get to experience this and no one can skip it until they have recognized that they are the ones who are in control to stop addiction if they want to. The discipline that this requires is a lot and someone who's got through with so many problems aside from gambling addiction is hardly going to overcome this and the rich people are not exempted with that.
from the people I talk too the poor usually go more for the thrill and are gambling solely on the hope of making more money
people that already have more disposable income and understand money better end up having some kind of system to manage bankroll and risk, they understand risk better and they avoid gambling when they aren't grounded and present (like when they're sleepy, anxious or angry)
these simple things already go a long way
That is it for the rich, they have a system and they understand how much risk they should take. And if the bankroll that they have started with losses, they have a way to recover them.
While the poor, they don't have those and if they lose, they don't even know how to take it back from the other ways of earning money that they have compared to the rich folks, they have ways.
