Studentst and stimulus number 3

Student graduated from college May 2021. HAd full time job beginning may , earned 24k through year end.. 

His work pays his health premiums. so hes not on mom and dads. he does live at home.

 so question is pertaining to stimulus 3?.  his parents will not claim in 2021 even tho by virtue of his being a student for 5 months they could.   Their income is too high for any education benefits and no other child credit.  so student now independent will claim himself.  

SO in software . if i check yes someone could claim him then no rrc 1400( by virtue of them support for five months). I f i check no then he gets. as well he is now eligible for the aotc for his final semester.   This sounds too good to be true. 2500 plus 1400 by checking the right box.  AS aside i know of several friends whose students were declared " independent in ' in 2020 to get stimulus 1 and 2 not saying its right but it was done(not by me). 

so is this easy money or am i missing something?  does the " could" claim him even tho he has earned enough money by 2021 end to claim himself cancel all my checkboxes.
