That would be the most stupid thing to do, specially you are bound to affect the relationships with your friend and family just because you don't pay them back that amount incase you end up losing.
You are not having the ability to pay them back because every time that you win, or making some profits, you are continuing to gamble having the thought that you could make more, but the thing is you are not, that is why it is important to save if you are making some profits, for you to be able to pay someone you owe a debt, to take care of the relationship that you have between your friends and so on.
