To start with I wouldn't build a future that would see my child going in to gambling at such age. Even if it happens that he gets in to gambling. It will be base on fun for his favorite game and not an escape route from poverty. An 18 years old child should be more concerned and bothered about their future rather wanting to indulge in to gambling. It all goes down to the kind of future you prepare for your children. Parents need to take up their responsibilities and not let this be an option for survival for their offspring.
It’s not always about escaping poverty. The rich also gamble and their stakes are higher than the average person would like to spend on gambling. Children are easily influenced and with the rate of online streamers promoting casinos, it is easier to teenagers to develop interest in online gambling. You cannot stop them from using the internet, the best solution is to educate them on the dangers of gambling addiction and hope they see things from your perspective.
