It's really hard to say with AlphaStar, because it depends enormously on what type of APM constraints the developers put on it. As much as I love the strategy of StarCraft, brute force is incredibly important. Serral, the best player in the world at the time by a wide margin, played some fun games against a few lower level European pros controlling the same opponent and it was so lopsided he quit after ~2 games.
If AlphaStar is allowed just slightly too much micro it's easily world champion beating (eg the version that killed TLO in the original demo, it was winning fights that should have been blunders), and too little and it can get squashed by regular GMs.
I don't know how the competition can ever really be calibrated to be fair. The latest version of AlphaStar was fun because they tuned it to be good but not unstoppable, but I have no idea if those were 'fair' settings or not. Maybe AlphaStar was too handicapped.
