I understood what she was saying, but her French accent made it difficult. Closed captioning is helpful, but it is done by a computer and often yields incorrect words in the speech recognition.
The bottom line is that not even the top players, playing at their best, perform at the same level as the top chess computer engines. An average Grandmasters would match computers roughly 50% of the time, which is how Hans Nieman plays most of the time. However, he has several games that are 100%, which is unheard of, and a few others that were in the 90s.
I was on Hans Nieman's side, viewing him as an up-and-coming 19-year-old. He is either occasionally playing like a genius or is occasionally cheating. It would make sense that he would not cheat all the time because that would be too obvious.
I hope that this is not true.
It is possible to play a perfect game if your opponent plays a bad game because it makes the choices more obvious. Against really terrible opponents I played perfect games according to the computer, but I didn't have to think very hard.
Yesterday, I studied one of Han's better games because it is very instructive. (https://www.youtube.com/watch?v=wCJ0uIAlreA) The youtube chess personality stated that he didn't think that Hans was cheating, because the moves were the kind that a good player could find. This may be true, but if a player has too many aberrant results then it looks suspicious.
In this long video, Hikaru Nakamura gave his opinion on the first video, comparing the results to his own games:
This is a shorter video doing an analysis that is worth watching:
