An addict's budget can only be all the money they can borrow, through appropriation as well as their basic source of income, advice still has their ears but their hearts prefer to hear the sound of gambling, the sound of winnings after a bet and their lives are also left with chaotic disasters, almost no one wants to reach out to help such people, sometimes gambling addiction is identified as the scum of society. Under any circumstances, our budget for entertainment should not go beyond what we admit, a little flame of borrowing can burn us to ashes.
I can allocate 20% of my total monthly income to entertain myself in some games. I don't think that borrowing money for gambling purposes is the best way to profit from gambling. The risk of loss is always real and bad debt is something that is most likely to occur if all the money borrowed is spent on gambling. If you really believe that a loan is okay if it is used for gambling, then I believe problems will come because of it. So far I've never done it and have no plans to do so.
So you made the right choice, because to borrow money for betting is totally discouraged. Besides the debt that is almost sure to go to the moon, the gambler also puts his life under risk if he isn't able to pay it back. There are many people who got murdered for not paying a loan back. Furthermore it's not dangerous only for the gambler, but for his family as well, as everyone related to the borrower will be on the radar of the loan sharks.
People who don't have money to gamble should just not gamble. This way they would be safe and sound.
