I don't know that our guest is asking for homework help. It may just be that this person simply has no ideas as to where to begin.
In any case, I would suggest that you learn programming, first and foremost. If you have never programmed, there is no way to know whether you will enjoy it enough to want to pursue a career in coding. Start off with a language like C#, JavaScript, or Visual Basic. Expect to spend a couple years learning how to program the language you choose. It won't be before then until you can decide whether to pursue a career as a game developer.
In the meantime, all the best, and let us know if you need additional information.
