I agree with your opinion about a young age should be stopped from gambling, but the problem is they can easily access every website with internet connection which available everywhere. They can access gambling website in the cafe or the malls.

I think the governments which are prohibit gambling in their country as trying hard to block every gambling site so people especially young age cannot access that site but you know, the internet connection is not hard to find in today. Perhaps, it is our jobs to take care of the young age around us or even our kids to stay away from gambling. I am sure if we can explain to them about how dangerous gambling games for their life, they will understand and they will obey us.

Besides that, we need to make a friendly approaching to young age, so they know that playing gambling is not good in their ages and even it will risk their life too in the future. And soon, after the young age realizes the risk of gambling game, they will become aware that they don't have to use gambling as one way to having fun and there is any other activity that they can use in their free time.
