Hans is clearly cheating. Comparing his past games against what an engine would do is pretty damning. Chess engines are far superior to players and the best players in the world top out in the high 70s percent correlations (Magnus averages around 70%).
Hans has a string of games at 100% correlation[0], meaning he's playing perfect games. Past players who achieved this later went on to admit to cheating[1]. Magnus knows this because he owns part of chess.com and presumably sees the data.
Magnus has a lot riding on his statement. He wouldn't make it unless he was sure.
