There is "copyright take down requests" which are DMCA takedowns and gives the uploader strikes against their account and there is Googles own copyright system (Content ID) which Google would rather have right holders use (as they don't have to issue strikes to the users) that allow the claimant leave the video up but get the analyics from the video, claim the ad revunue from the video, mute the video (in cases where its an audio claim) or remove the video.
When you get a claim on the latter system (Content ID) you don't get a strike on your account but if you appeal the claim its (normally) upto the claimant to decide if your appeal is valid or not (sometimes YT does step in an say "yeah its fair use, have your ad rev back" but that is not the norm).

These takedowns are actual DMCA takedown requests. (even TeamYouTube are telling him to issue (valid) counter notifications to these claims - https://twitter.com/TeamYouTube/status/1306733040211824645)
