I am quite sure that the guy is just making excuses when he says that he is gambling to make money for the hospital to save face. If someone needs money, he will not gamble it instead he will ask his friends for financial help to add to the money he is currently holding that time. Only a gambling addict will gamble the money that is allocated for hospital bills and say the reason that he does it is to increase his funds.
...
but maybe what is said is the truth because not everyone has friends they can ask for help when they need help with money or they feel too uncomfortable when they want to borrow money from their friends, so this leaves them with no choice but to gamble their money to be able to get more money.
but whatever it is, gambling to get money is something that is not recommended because when someone gambles to get money, it means that they are set in their mind that they must be able to win. when they can't win, they will keep trying, and at that point he will get caught up in gambling and become addicted.
