how feasible is it to have a data science career with a career gap in technical field of 10yrs

I would be grateful if you could offer your advice on whether I should pursue a career in DATA SCIENCE. Is it advisable for me to take your course?

I wish to start my career as a data scientist, but I have concerns regarding my profile. I have a career gap of 10 yrs in the technical field. I graduated in 2011 from MDU University with 80% marks and got placed in Infosys. I worked there for six months and left my job to prepare for UPSC. In the meanwhile, I started volunteering with a local NGO. In 2015, I started my NGO and since then have been managing it. My query is If I manage to acquire the requisite skillset and create a good GitHub profile and Kaggle contributions, how difficult is it going to be to get a job for someone like me. As you are privy to this industry, can you apprise me about the framework and process of navigating the situation?

Looking forward to your guidance. Please do reply.
