I would put celebrities in general and YouTube influencers in a completely different category.
I think there's a big difference between some random celebrity ---say an actor, athlete, or musician --- pontificating on things they don't really have any clear grasp of, and political comedians like, say, Lenny Bruce, George Carlin, Stephan Colbert, and Bill Maher.
The former is just preaching to an audience that's already there, an audience composed in large part of people who are going to listen and believe what they say just because they're fans. They don't need to be accurate or even make sense, a lot of people are going to be nodding along anyway.
A Youtube influencer can make a living spouting nonsense as long as it's popular nonsense, ie., nonsense with its own built-in fan base, nonsense that already has an audience that the influencer can exploit.
On the other hand, a political comedian makes his living by pointing out the obvious, and in order for something to be obvious it has to be grounded in truth.
A political comedian's celebrity depends on his ability to make us aware of fundamental contradictions and absurdities in our society. Unless he can do all that effectively he doesn't have an audience.
In a nutshell I would say that it's a political comedians job to make us think, whereas the people in those other groups just tell you what to think.
