1000 ELO. Am I now an intermediate?

I guess you are now an intermediate beginner 😃

Intermediate is intermediate between beginner and strong club player, which is round about 1900 FIDE upwards. A lot of people with 2200 rapid, blitz or bullet ratings on here would be barely out of the beginner stage at otb matchplay. They certainly wouldn't be strong and might be middle-ranking intermediates.

Step by step, improving is difficult. You are in the right path.

Rare. Not unprecedented. Twice most days. The phenomenon of the broken clock.

In my own opinion, 1,000 is still considered beginner level.

That is not true at all you must be very under rated 

Looks like somebody misspelled post-grad [sic]. That's okay. I'm just auditing this class. I think postgrad refers to advanced studies. My uncle taught postgraduate microbiology courses at KU. His reputation preceeded him for being a tough grader. Students avoided his classes if they could.

There is undergrad—those working on a bachelor’s degree.

There is graduate school—those working on graduate degrees.

Postgraduate usually refers to advanced research after a doctorate. Postgraduate work is supervised, but does not consist of classes and is not graded.

I teach undergraduates and occasionally have an MA student, as they are allowed a small number of undergraduate courses. So, I’m in no way a postgrad professor. 

when you first create a chess.com account, you can select / get placed in : new to chess 400, beginner 800, intermediate 1200, advance 1600, and expect 1800.

You've forgotten us Nevergrads. Again.

FIDE rankings never applied to reality, just to the 1 percent of people who join FIDE.  Sorry to break that to all the FIDE worshippers.

USCF class rankings group everyone U1200 in the "Novice" class

All chess organizations fall under the same top one percent trash.

I am about 1000 to 1200 here and I beat everyone I meet in real life.

I guess intermediate is about the same as medium or medium rare?

If you play you slay. You've had over two-thousand games on here. That's enough to make you a real life chess menace.

I just play too fast lol.  

So maybe split the difference and call it "advanced beginner"? Most people don't start at 1000, they have to climb to get there.

No. Most players here are beginners. The quantity of beginners does not redefine intermediate.

And all chess oranizations are where it matters.

For the longest time, OTB is the only thing that has been relevent and that still hasn't changed.

Online chess.com is just practice. It grants no titles and has no affilliaton with OTB.
