This is a >11 minute video, which winds around the truth, but ultimately the creator trying to reason about what's going on... But his conclusions end up being incorrect. Don't waste your time.
These videos are made to gauge interest in game ideas by making up ads, and the seeing what engagement is like. If people will click on an ad to download a game, they don't know if that game is real, but their clicking says they are interested. And if it's successful, the game may incorporate the idea as mini game, within their existing gams, and see how it pans out in actual game play.
This is idea testing, it's not deceit trying to hook you up into their existing game by baiting you with something else. That might be a secondary side effect but this is not the primary goal.
This creator is totally misreading this.
