Well, that's true, you can be a professional YouTuber showing your gambling on your channel for example, because you are getting paid for the ads that you run on the channel.
As long as you actually get money from something you are doing, instead of paying for doing it, then you are a pro, a professional. That's how you "turn pro", when you start making money with anything.
this means that the YouTuber is deceiving many people, he or she is not gambling but making money from. it is important for us to pay close attention to all kinds of video content on YouTube, if it turns out that these videos can lead us to become gambling addicts then it would be nice to avoid that especially for those who have weak emotional control, it is not impossible in the future they will do something who are stupid when gambling turns them out to be ruined.
I do not see it that the YouTubers are deceiving us. Many celebrities are hired for advertisement purposes and it does not really mean that the celebrities are using the product. For YouTubers to promote gambling on their channels doesn't mean they are gamblers and neither does it mean that they must gamble. It is advertisement that is paid for .
For instance, even here in the forum, I have seen people wearing gambling signatures in this forum but yet they don't know what gambling is about.
