is becoming a dr indeed a high roi profession?

im going to join a deemed uni this year for mbbs (its fees is about 60L) and im unsure of what my future is going to look like after 6 years. do doctors really earn that much for my lakhs of tution fees to be worth it?
what i rlly want to know is that after my pg, what will my salary look like? i want to think of the long term, in that sense this field js feels safer..
am i wrong to think that way?
please js give ur unfiltered opinions

(also wanted to explore if there r any job opportunities after i'm done w mbbs.. pls suggest i'm always open to new opinions)
