I am asking for those people who don't have any skill or job ?
I do not see this idea feasible in the long-run given the nature of gambling that is highly unpredictable.
When we mean by household expenses, this include everything from your food, lodging, electric bills, and all other monthly expenses. These type of expenses are what we call running expenses since they consistently incur every month. If you attempt paying them with something that is unpredictable, chances are that you will incur more obligations and credit in the long-run.
The only exception is if you're a gambling operator or a casino dealer, it's still a job and your income comes from your being an employee but playing gambling to sustain your household expenses I don't think it's possible even if you're living alone, you will become a pauper and penniless, so if you want a decent life, get a job and only allocate money for gambling, and enjoy playing don't expect or try hard to win.
Unfortunately, just as OP stated, people who has "no JOB and SKILL" so the exemption you've presented doesn't apply on this scenario. Other than having an extremely high luck or probably winning an insanely high jackpot which will be enough to cater all your needs and necessities. I cannot think of any other ways for this to work out especially if you don't have any skills or job that will serve as your backup in case you lose.
