Children of today are very clever. They can easily figure out the strategies of how to manage and who to inform or request so that they can do those things for them. I have seen some gamblers who are minors but they gamble online. When they are asked about their KYC, they do those things through others. That is why it is not possible to stop them from gambling in any way. In this case, if the parents of those minors check all their devices well and advise them to refrain from gambling, then it is possible to control them to a great extent, but there is no possibility of stopping them completely in any way.
Yes, you can say that it is something that they can do and evade certain controls, but it is a fact that children should not have access to these games, I do not know if parents want them to be entertained they should focus on sports, my 8 year old son sticks very hard to playing games on the phone, but they called him up to the national football team of my country, apart from that he is the best in the class, how could I say no to certain things? However, I know that he is not in casinos or something like that, the controls in my country are bad, but I am sure that he does not have access there, because I check his phone.
