Can anyone pls guide me in explaining the true means of PSRR and verify the validilty of the previous claim.

the
PSRR is the rejection that happen at the o/p due to imposed noise on the supply
while what you have calculated "and a 20% supply voltage variation gives a around 0.5mV" is called the
power supply regulation i.e if the supply voltage is drifted how the output voltage is changed this is far from the PSRR in meaning.
but i think they may be related by somehow i am not sure
