I am working in one a private company.
Tier 1 of the SSC CGL 2021 will be held in April. I’ll have two months for it. If I achieve a tier-1 score of 165 or more, I will resign and focus solely on UPSC preparation, since I will have a backup plan in place because the CGL-2021 can happen in August 2021. (hopefully). If not, I’ll continue to prepare with my existing job, save some money, and then apply for UPSC because not everyone has the opportunity to go full-time after college (I hope you understand).
Given that you are unemployed, I recommend that you prepare for SSC CGL up to tier 1, score well over the cut-off, secure your rank, and then apply for UPSC. Believe me, you will feel more assured.
If your family has enough money to sustain you, however, they will go straight for UPSC. Because, to be honest, UPSC preparation these days requires money (might be in lakhs).
Wishing you all the very best.
