Jokes can have true meaning behind them. Even though the video is a joke it's obvious that Max still truly believes Sonic is a "toon" like Mickey and needs to be rendered in hand-drawn animation. And the joke is that he's offering himself as dateable based on his skills and knowledge as an animator.
So yes it's a joke, but it's also an attempt to criticize the Sonic movie and highlight how how animation expertise are useful for an animation job, not necessarily for the movie.
TL;DR just because something's a joke doesn't mean it's not an attempt by an animator to get hired. Observe Titties McGee over here who's part of a demo reel from an animator trying to get hired.
