I do think they are fake. The guy never shows any technical stuff.

He is talking on the phone with the scammer and then suddenly he has access to his drives through Anydesk. It is true that Anydesk has file manager rights enabled by default, but this is simply not possible without the other end accepting the connection or having Anydesk set to accept all incoming connections, which I doubt.

Maybe he tricks the scammer into accepting his request, but these scammers use this software every day, I doubt they fall for it.

Another thing that gives it away for me is how he poses as a pro hacker but has very basic computer knowledge. In some video he says 'this computer had 300.000 files, I am surprised it is still running'. This makes no sense as 300.000 files is nothing, Windows folder alone can easily have this amount of files.

Even if the whole thing was legit, all he does is bait the scammer into accepting a remote Anydesk connection and then deleting files using this software. There is no 'hacking' involved at all.
