My parents claimed me on their return last yr & I didn't get stim money. If I claim myself on 2020 taxes can I get the money through the recovery rebate credit?

I am 21 y/o and a FT student. I can also claim the AOTC  this year also if I am my own dependent, correct? Parents are OK with this. Not sure I paid 1/2 living expenses as I lived at home all year.
