25 years old confused about my career.

Hello. I am 25 years old from India. I have no degree no work experience. I will do a distant degree (bcom or bba) and simultaneously learn digital marketing from one of the online courses/cohort programs like wscube, simpililearn, bluetick academy etc.

I have decided to do digital marketing because I have a good gaming laptop with good internet connection, sitting idle at home doing nothing and turning into a financial burden on my family. I want to learn some skills, move out of the city, comfort zone and start earning and become financially independent.

What skills should I focus on developing if I choose this career ? I have tried learning data analytics, coding through YouTube but they are not structured and due to lack of guidance I am confused. Finally I have decided to do digital marketing with proper training and guidance.

I am worried about the age factor and no previous work experience and qualifications or degree. Will there be any setbacks due to this?

Is this the right decision and career choice right now on this stage or should I look into something else like graphic design, video editing, coding, data analytics, trading, music production, law etc that can be done with my laptop with internet connection.

Or should I go to a college and do a proper degree like btech, llb, bba, bcom etc.
