The government will not help us if we do not help ourselves, they are now carried away with the sweet money made from gambling operators and except you are in a sane country, but the consequence is not always known ahead to forestall it. This is where parents come in, we may not be able to win the hearts of all our young children this way but we will at least try to win more than half of them if we continue to educate them on it. Gambling is addictive and ruining for the young ones, even their school fees will not be spared. 
The best way to protect children is to explain to them that gambling will not allow them to earn anything. Even for experienced players this is a difficult task, and for beginners who have no experience and no knowledge in this area, it will definitely be a bad idea. Minors will most likely listen to their parents, but with adults everything may be different, they may not even admit that they want to try to play, but this will be their personal experience.Children are likely to listen to their parents and learn from what they have to say, though it is completely the opposite when they become teens and they start to get more rebellious and question the authority of their parents completely. Therefore, we must educate our children about gambling and consequences of reckless gambling before they become teens or young adults.
Many parents do not even mention gambling to their children and those children end up discovering gambling by their own after their puberty, when it may be already too late for them to listen carefully and understand their parents are trying to educate them and save them from a future of misery. It is better to talk about drugs, sex, alcohol, gambling and other things to the youth when it is due for us to do so, than continuing to perpetuate a taboo and allow lack of information to hurt them when they are already grownups.
