Even a professional prefers to finance his own gambling and does not want other people to finance his gambling, although perhaps many greedy people want to win big money but are limited by gambling sites so he chooses to finance someone to gamble for him, even though it is risk-free but still financing anyone is very not recommended because it is better to gamble with your own money rather than using other people's money.

What you said is also true that a good principle is not to ask anyone to pay for the gambling we play. Using our own money and our own risk is better than looking for risks with other people's money that we don't know whether there will be problems or not in the future, it's best to avoid anyone who want to finance the gambling we do or we finance other people's gambling. If you don't have money, don't gamble.
