Civil Services vs Private Job

I have just graduated and started working in Bangalore at a core company(electronics related) with 20L in hand and another 20L in bonus, stocks etc. But my parents are asking me to write Civil Services, which I like as equal as a private job, but after I gave one upsc attempt this year, then I understood that UPSC requires lot of luck too, as the most of the questions are dynamic and no one can predict them. This is also said by many UPSC toppers too. Instead I am thinking to continue in private job and get salary hike or promotion every year by working hard or by switching to other companies which has good opportunities. Can anyone give insights on whether I should pursue Civil Services or should I work in private firms. Please also give reasons. Thank you in advance
