All this applies to a very large extent to fairly young people and, of course, to adolescents. In this case, there really should be some control on the part of parents or older brothers. Because of course such a young person may become addicted to gambling and may even begin to experience an irresistible desire to gamble more and more. So what you said is important for young people.
If we talk about a person who is a middle-aged or even older gambler, then I think that such methods of control and assistance will most likely not help a person effectively get rid of gambling addiction. Of course, this is very difficult for family members and for the player himself, but I think that the help of specialists is still required here, that is, those people who know well how all family members and the player himself should behave in order to recover from such a gambling addiction.
Young people with big curiosity will make them learn about things they want to know, including about gambling, by trying to start gambling. At first, maybe they only gambled with a small amount of money, but because of the influence of their friends who had a lot of money, they finally followed the invitation and in the end, they sank into gambling. That is why the role of parents and other siblings is needed to look after each other and supervise so that if there are deviations from family members, they can immediately help them.
And yes, specialist assistance is certainly needed when the family feels unable to help people who are addicted to gambling but still, the role of the family is needed here to accompany the gambling addict to recover from his gambling addiction. Otherwise, it is difficult for a gambling addict to recover because he feels alone fighting his gambling addiction. But as long as that person can play gambling responsibly in that they can stop themselves at any time and are not affected by anything when they stop, they can still gamble within limits.
