The difference is that Genres are predetermined by the information providers, and generally widely accepted as being a genre.
Tags, also known as keywords, are anything you want them to be. Use them any way you want, and there will probably be some overlap with genres, depending on how you choose to use them.
Leave Genres to what is being scraped, use Tags for your own personal lists.
Here are the genres used by IMDB, TMDB and TVDB...

Do both <tag>Vampire<tag> and <genre>Vampire<genre> get added to every relevant .nfo file, or does using the <tag>Vampire<tag> in one file create it for use generally? Obviously, any video that qualifies, except possibly the "first" one, would have to use one of the two, or possibly both. I did not write the code, so I don't know, but it certainly would be possible for KODI to create the tag based upon the first time it gets included in the library, enabling the tag itself to be used thereafter. It also would be possible for it to be written so that the <tag> tag and only that must be used every time one wishes to include a custom tag. It is also possible that the <tag> tag creates the tag for only that video, and then one must also include the <genre> tag to make it a genre. Perhaps something else; I don't know. The Wiki certainly does not make it clear.
You are starting to confuse me. I don't really know what you are after.
Yes, you only need to add the tag and/or genre to a single movie, then that tag and/or genre gets created in Kodi and becomes available and visible in Kodi. Of course only that one movie will be listed in that tag or genre, so you then need to add other movies to that tag or genre if required.
If you have 10 Vampire movies, but you only add one vampire movie to the <tag>Vampires</tag> tag, then only one movie will be displayed in that tag in Kodi. You still need to add the other 9 Vampire movies to that tag. Same for Genre.
