There's nothing much that can be done to ensure exposure to kids in gambling.. the world is growing and these things spread like wild fire. The kids these days are learning from pairs and not all their parents are available to monitor who they mingle with. The internet again is something that cannot be eliminated from the children. They learn a lot from the Internet. Though most countries restricted under age gambling, but these kid might find a way to bypass these restrictions placed on them and gamble. Tg best thing I think can be done is to actually advice them on the negative influence that gambling at a young age can cause them. Aside that. Nothing much can be done.
