Gambling using a loan money is a big NO. The thing about using loan money for gambling is when you lose, you lose twice. It just doubles your regret, doubles the guilt, and doubles the money you lost. In the worst case, you will be possibly get into debt and that is something that we want to avoid.
If you take a loan to gamble and you lose, you will regret the bet you lost and the loan you took to place the bet. You will start thinking about how you are going to get the money to pay back the loan you took to place the bet, which might end up even affecting your health condition. Some people might end up going for another loan just to pay back the loan they took to gamble, and when the due date for the fresh loan they took is close, they will end up taking another loan again from another place, and they are already in debt. They might not be financially stable any longer. That’s why it’s dangerous to take a loan to gamble.
It depends your financial capacity on the effect of loan to your gambling experience. Some gamblers ask for short loan because they still waiting for their salary. In this case, they won't experience the scenario that you described because they have money to pay for it. They will just pay for additional cost on interest but nothing big changes than regular gambling using own money.
You will only be on disastrous state if you ask for loan without a way to pay it back aside from returning the money that you loan for repayment.
