Will I be guaranteed to receive the 3rd stimulus check?

I am a full-time college student (age 22).  I have $10,000 earned income in 2021.

I have never received any stimulus check, since my parents claimed me as a dependent every year.

Due to their high AGI, my parents are NOT eligible for stimulus check.

 

If my parents don't claim me as a dependent on their 2021 tax return, and I file my own tax return, am I guaranteed to receive the 3rd stimulus check ($1,400)? 

Will I receive any stimulus check at all?
