Am I a Beginner??

I am rated 1450 average on Blitz and I still consider myself a real beginner in chess.
You could look at chess in the form of stages... I remember when 1150 players were tough in blitz, but 1200 were simply unbeatable
afterwards were the 1400s that were simply unbeatable, and now I play around with them, occasionally beating a few 1500s here and there. I remember I beat a 1900 in another account once and I was ecstatic.
Anyways, most likely at your level you could beat most people in a social gathering, which in itself is already a good achievement. But you still got a long way to go
