Loan is more suited for people who have sources of income or properties that they can sell to back back the loan if things don't work out well for them, that's why I agree that taking loan is not for those who are broke or those who are jobless, taking loan is best for the rich.
If you don't have a job, do not go near a casino, the solution isn't you trying your luck out in gambling, the solution is your income stream, find something that will bring you money and get your shit together first, have some savings in the bank and take few percentage of the money you are making for gambling, it's going to be a flawless experience.
Well, when I think of borrowing money just to gamble, it's like suidal to ourselves. I know what that means. Are we stabbing ourselves? This style can be called bad debt. It's not a good move when a gambler does it, even if we say we can afford to pay the debt.
As long as you can, don't plan to do it. It's not bad to take a loan, but use it wisely, not for gambling. That's all I can say honestly: don't even try to do it.
