In the previous jams I have participated in, the Brackeys Game Jam 2020.1 and .2 as well as the Community Game Jam, the required ratings were 20, so I'd say it's the same here.
Just the results page for the jam. The top 10 for the jam results and the top 10 picked for the video were completely different. The ones that were shown in the video for GMTK were selected by Mark Brown from a shortlist of the top 100 games from what I can recall.
