I suggest you look into taking some online courses through Udemy or Coursera to see how you like it and what you can do. Coursera has a course for game development in Unity through Michigan State University. There are 5 ( i think) 4 week courses to take you through Unity and game development from 2D all the way through 3D games and would be a good intro point to see if you like it.
Game development sounds like a fun thing to do, but lets be honest here... its a lot of work and a lot of effort to make a really clean, nice, and functional game that you can be proud of and will have a nice little following.
I am currently working on my first as a side scroll RPG and will take me some time to create and develop before I even feel ready to push it out.
Good Luck and Enjoy the Process!
