Kind of. It shows he is a liar. Maybe that wakes someone up. News showing that political leaders and figureheads lie about even the mundane is good reporting, even if the topic is dumb.
I think the more important insight is how desperately he is trying to appeal to the young male demographic, and going so far as to pay a pro gamer to boost his account in a video game so he can pretend to be one of them.
Why? Probably a lot of potential reasons, but anyone with even a little bit of critical thinking skills should immediately become suspicious when they see that. Because whatever the actual reason, it probably isn't good.
What's really funny is that he still could've faked it. Like, it would be simple to talk on face cam while someone else plays. This showcases his deep narcissism that he is buying his own pathetic hype.
The most charitable answer is sad: that he sees himself as one of them. It's entirely possible that he thinks of himself as essentially a 20 year old who loves video games, drugs, and trolling.
He’s trying to build credibility among younger audiences through the only thing they give a shit about: video games. It’s more anti-propaganda than it is “news”. And, really, most news is some form of propaganda or anti-propaganda.
