I think any experienced gambler will not be fooled that such a video is real. The point is that these types of tricks are trgeted to people who have no experience and think that winning at a casino is easy. After seeing a video like this, they deposit money and usually lose everything very quickly. It should not be like that.
I am afraid that happened to many people out there because many of them do not control themselves and will tempt them to play gambling with less control. We see many people getting trapped because of their ego and think that they will have the chance like those people on the videos. If they can spend some time learning more about gambling or controlling themselves, they will see that it is easy to get tempted but difficult to avoid getting tempted because of money.
