That's the purpose of advertising, to tell white lies about it so people would use it (either a product or a service) by paying influencers to promote it even though the influencers doesn't even really use their products. They only do such marketing because in that way, they could easily persuade people to appreciate their products and make a huge sale.
In YouTube, there's a notification or warning if a video is not suitable for young people like below the legal age. I think it's the parent's responsibility to always watch their children's activities online.
I also do remember LL Stylish promoting Stake on his twitch while playing league of legends. I'm not against it but he should've considered his audience which is under 18 mostly and he had over 10,000 Viewers at the moment that advert went online, Not counting his Youtube video containing the same Ad had over 200,000 Views, Casinos can't be blamed for it if the will power of people running streams isn't strong and they're easy to give in to these temptations.
That video should be restricted to user below 18 years old and there's a feature of this in Youtube so for sure no minors watching that advertisement. Fake bets are real, many are into this just to attract gamblers so its quiet risky if you get into that site because of that fake bets. Also, if those youtuber feature their earnings you'd better to think again because they might be part of the advertising team, so technically he's playing the money of casino.
