It somehow reminded me of stories about some gamblers who resorted to borrowing money from their relatives and friends to continue gambling with the hope of winning back the money they lost in the casinos. I guess it is better for gamblers to learn how to stop gambling and cut losses early if they found themselves starting to borrow money to gamble as the chances for them to recoup their losses are very low.
From very low to non existent as I have yet to hear a story of how a homeless person in full debts managed to go to the casino to win big and to pay back all debts,win money and to buy a mansion for him to change the life from this to that.This means that most of the times,for me always whenever a person borrows money it is directly going to ruin himself if he put that money as a deposit in any casino and plays there.There are simply no stories of such persons and this should be enough to have as example that the statement "if you quit that's when you lose" maybe related to other fields in life but got nothing to do with gambling.
