It is possible.
I have seen some videos on YouTube which are alledgedly done to show people who gambling addicted people suffer the consequences of their recklessness, but there is something off about them. In many of those videos there is much emphasis on how they managed to score very high wins, before they got greedy and end up losing it all after a relatively short period of time.
I am not affirming anything, because I don't have any proof those videos or those people are being sponsored or being paid by casinos to attract more gamblers, but it would seem to me the trick is to show both the big wins and then the downfall of those addicted gamblers,.so the viewers have the impression the could "stop at the right time", unlike those gamblers in the video, prompting them to try gambling for the first time or turning them to active gamblers from passive/casual gamblers.

Just my personal theory, I could be completely wrong.
