To be honest this is quite funny, at first you borrowing that money how certain or what are the odds of you winning with that money you borrowed, because you thinking of borrowing money to gamble shows that you don't have any money with you left to gamble, might be due to various losses doing your gambling section.
You know that is two different thing losing your money and losing someone else's. And this is truly against the rules of gambling with money you can afford to lose , and this time you ain't planning to only lose money you can't risk but also someone else's money. Because you losing your money you can easily move on and continue with your life. But when is money you borrowed that could be another case, and you may endup putting yourself in debts. Adding another issue to the previous one.
That why you have to gamble with only funds you can afford to lose, and in any way you endup losing it and you see you don't have enough money to continue you put some break first till you have enough funds to continue than going on borrowing money to gamble.
