Grats on 120k!
I remember how famous I felt when I had 50-100 subs in 2009, I did a lot of sub4sub back then though, but those people actually watched my videos.
I have no idea when you're famous or not, I know that most of the popular YouTubers dislike being called famous and I thought that they said that they didn't want to be treated as celebrities (not sure if they said it) But I understand that because I'm sure that most celebs dislike being famous as well.
But I don't know when you're famous or not because you can, for example, play in various movies and tv shows and still be unknown, even if a lot of people have seen the movie or show.
