is it fine to go to college at the age of 28

so a bit of backstory

i am a 3rd year mbbs student and although i am enjoying the studies i always wanted to study history or literature in a university as compared to a medical college and only entered this field due to parental advice and financial security

however i still want to pursue the cool university life studying something i actually enjoy so i am deciding when to pursue

my plan finish mbbs by the age of 24 then finish pg by the age of 28 then write cuet or other required exams and go to my dream university

is this plan ok ? it's ok if i start my career 4 years after pg at the age of 32 will it create some impact on my life , i just want to enjoy 3 years of fun college life before i enter the workforce and start that part of life

please don't consider it as a joke and give me some good replies
