Of course no. Why would you gamble a money that isn't yours, you're taking a loan because you've told to the lender that you'll pay now how can you pay if you're broke because you lose it on a gamble? Gamble is 50-50 even if you have a mindset of what ifs, it's not very practical and you'll just create problems with the one who lend you money.

There's no game that's worth risking unless you're super good with poker or maybe have a good analysis on sports bet. But even if you have, it's very unethical, lowest of the lowest, to borrow money just to gamble.
