It's not good to work extra hours to manage money for gambling, but if it was for supporting the family or managing finances, then it would definitely be good. Is it any kind of income to earn money by working extra hard and then gamble with that money and then lose money after betting? There may be other ways to have fun, but it is not something that has to be done with money earned after a lot of hard work. If he had worked hard, of course he would have saved his hard-earned money, but instead of doing that, taking a gamble is an uncertain and unguaranteed possibility that is not worth supporting under any circumstances.
