Most people, yes, they might not know it is torrenting, but many would interact with it from day to day.
Since the UX is basically the same as downloading from a server: you click on a link, and a software pop up with a progress bar and everything.
In fact, I think most Chinese downloaders (thunder, and some tencent crap) can both torrent and download from a centralized server, and sometimes they will use torrent to accelerate the download when applicable.
