As others noted - it's really a matter of personal perception. I don't know who used the term with you but "you have arrived" are the same words said by Stieglitz to Eliot Porter. Stieglitz initially rejected Porter's work from his gallery and supposedly this influenced Porter to double his efforts and find his photographic "voice".
In this instance the proverbial arrival is about Porter achieving recognition by someone he admired and respected (not to mention Stieglitz held the keys to commercial success in the photography art world in those days, at least in Porter's genre).
So - either define "arrived" for yourself (being widely published? making a full-time living? capturing that once-in-a-lifetime image? being accepted by some high-brow gallery?) and focus your efforts there or, if you're happy with your journey thus far - keep at it and let others worry about semantics.
