The biggest mistake a gambler can make is trying to get rich with gambling, this mindset has a way of propelling gamblers to lose...The reason why it's easy for gamblers with such mentality to keep losing is due to greed...a lot of people blame their lack of self control on dopamine rush but this is just an excuse for indiscipline and it's one thing that keeps them mentally trapped, it's all about having self control
Another reason for this, is ignorance, a good amount of gamers don't think or picture what's life like being responsible. The term look weird to them and doesn't fit into their perspective of what gambling should be, so they end up making grievous mistakes out of no prior training on how to deal with the excessive desire for wealth through gambling.
I agree with you, a irresponsible gambler only thinks that gambling is an important part of life and a way to achieve success easily due to his ignorance of reality, this is just a manifestation of their irresponsibility and those who have this kind of mentality should try to stay away from gambling as much as possible. If you blindly chase after gambling, it will definitely cause huge losses for you at some point, so in terms of gambling, you must have a limited mindset here, as well as self-control and the ability to stop gambling at the right time.
