Exactly, when you put gambling last before anything in life, you will be a responsible gambler, because you don't see it as a means of income. Gamblers get addicted because they see gambling as a source of income which make them put it first in their lives. If only gamblers can understand that no matter how frequently they try to make profits, the casino will always win.
I believe that they will find a way which they can use to limit their losses and gamble with only the amount of money that they can afford to lose.
This is just a way to help you stay responsible gambling bit it doesn't guarantee you will surely stay responsible. You can do this and the few time you dedicate to gambling you still get to mess things up at the end of the day. I agree that the casino always wins regardless of how often you win and that is why they are still in business and never bankrupt.
There are people who make a living from gambling and are not addicted, I don't think making gambling your means of income is really responsible for addiction, it depends on the approach and the aspect of gambling in which you are involved nevertheless I'm not using this medium to encourage gambling for a living but a job at the casino could still stand In as making a living of gambling.
