Agreed, quitting is not an easy thing. Whether it is gambling or something else. The owner shouldn't have given money, just because he gave money the victim continued spending. If not, he could've left with what he had lost from his pocket. The trouble maker is the casino owner who knows well about the reality of gambling that it is not easy to recover the losses.
I agree but the gambler is also not thinking wisely by doing that, hence they are mistaken as well. Why would someone take loans and use them for gambling in the first place? That shouldn't be how it works. Nevertheless, the betting agent should not provide money to the gambler as it can lead to a really bad consequences as it has happened before. The gambler might find themselves in an extremely difficult situation where they can't even recover the money.
