Where do you live? Do you think you can turn this into a life-long job? Do you enjoy it? These are all questions that need to be answered first before you can make your final choice.
If you think you can scale it up and wanna do it then show your parents your income, tell them what you do and hope for the best. If you wanna stay on the safe side you start studying and do freelancing on the side.
Honestly, i would always do choice no. 2 - Not knowing what your average salaray in your country is and what your age is, its pretty difficult to get a good answer but its never to wrong to have something in your backpocket IF the freelancing route fails on you someday. And trust me, there will be those times. And they are not gonna be easy....
