As someone who started making games at 8 years old, I don't want to preach that you'll be miraculously "unstoppable in life", but it always helps to have a skill! Game development is an understanding of many things that will help in life (eg: Logic, programming, and maybe even some physics and graphical knowledge).
Definitely keep at it and try submitting your games to sites like GameJolt which will help you earn money through advertising revenue (they do the advertising for you!).
