You're not wrong, however the files being partitioned during the file transfer doesn't really matter as they're brought back together as one on your computer once they're downloaded.
In the context of F95 and it's games for torrents vs filehosts, advantages include no bandwidth caps (mega, pixeldrain), no throttling (uploadhaven, mixdrop), no ads, ability to stop and resume downloads (thanks to the partitioned file-sharing method you mentioned), and the inability for copyright holders to take down the file since it's not hosted on a centralized server that can remove the files at any time.
For some people, all of the above doesn't matter as they have fast internet and don't encounter the above issues, but for others it matters and torrents help.
