Constantly gambling leads to addiction for addicted gamblers videos will not affect them. They will not believe that they are going to lose they will only be addicted to winning. He should have been warned in advance that he would feel pain when he saw the end. For those gamblers who are not addicted the video is good physically and mentally they will be prepared and alert to control themselves before becoming addicted will enjoy everything very easily.
This is why more awareness of gambling is important but the governments and NGOs are doing little or nothing about it. Private people can't always have the needed resources to go around to tell and help people regarding gambling, especially the cons attached to it, which will be a warning before they start gambling at all. This is not about dissuading people from gambling altogether but letting them know the dangers of gambling if certain measures are not taken into consideration. You can imagine the person who knew the good and bad sides of gambling before he started and cautiously engaged in it with the full knowledge that this activity is dangerous if he is careless about it. Such will always be one step ahead of gambling in terms of being careful, unlike those who are just gambling without prior knowledge of it.
Such never knew the danger in it but always wanted to get that money from it. Even those who want fun from gambling should also be careful so that what they believe is their hobby will not be a trap for them where addiction through it will make their lives miserable. We should try to moderate things, and those who started gambling with prior learning and warnings could be better planners, budgeters/managers, and strategists since they know what they are in for is more dangerous than many think.
