Downloads are working and very useful on mobile - they give you offline version on a device that you can later watch. I click download on videos that I'm interested in morning and have something to listen to during commute without worrying about spotty connections and mobile traffic consumptions. So yes, file is downloaded to the device. If I want to download something to have it forever, I use yt-dlp on pc.
