I mean yes and no. It looks like a AI-generated image of Mr.Beast. Which is what he uses in all his thumbnails because he shills his AI image generation site.

It resembles him, that is more or less what he looks like, but it feels incorrect to say an AI generated image is an image of him. Before AI, all his thumbnails included him making stupid faces like this (because it was very effective). Now he, and everyone else, just uses AI images resembling him making stupid faces (because it is unfortunately still somehow effective)

The social media algorithms have turned most people's brain attention pathways into mush. Sometimes people get a shovel and a mop and start trying to dig their way through properly, but a lot of times they don't get very far before it starts seeming impossible to make useful progress. It's usually easier to just swim in the slop.

Either that or just terrible Photoshop. Seems to be what everyone is doing these days is just cartoonish Photoshop with bright colors for some reason.
