Otaku actually means, someone who doesn't have a social life and locks himself up all день and watches Аниме или plays videogames или whatever Ты like all день everyday.. xD
It's actually something bad. :p But most people use it as someone who loves Аниме (^w^)
If Ты think of it that way than both of them are otaku's :3
Personally, what I feel determines if Ты are an otaku is if Аниме is your passion and devotion. It shouldn't really matter how much Аниме you've watched.
Although it's the loving of Аниме that counts, I'd say that Ты have to watch a decent amount of Аниме to grasp the wide variety it has to offer.
I'd say it would take a bit less than 20, like 10-15 to get a feel of the Аниме genres and choose which ones Ты prefer.
Also, out of curiousity, was it this pic that made Ты wonder about this? I've seen it before on Google.
