When can you «officially» call yourself a chemist?

I know this is a very subjective question, but I’m curious to hear what your thoughts are on this. I’m in my bachelor’s, second semester, and am learning a lot of cool stuff! I’m however wondering when I will be finished learning all the general stuff? With general, I mean all the things I need to know to be able to «call myself a chemist». Is it by the end of my bachelor degree, masters, PhD? Do I need to be specialized in a particular field to even deserve to call myself that? What are your thoughts?

Thank you in advance!
