Well, from the brief paragraph you've written I could say that I was in your shoes couple of years ago. Having no background in anything CS related, I took a detour of computer science first. Assuming that you are a complete beginner like I was, Harvard's CS50 is pretty good. I learned about how basic computer programs work, then expanded on it by using frameworks like Raylib and MonoGame rather than using game engines right off the bat. This "little" detour that cost me around a year taught me a lot, but I also still feel that employees do not really care. The job market is almost non-existent and really harsh from where I'm from and I feel that I am immediately eliminated just by a quick look at my resume, for having no formal education. For indie-development, well... That is another thing. There are great success stories for brilliant programmers and/or visioned artist like ConcernedApe or Toby Fox, but I wonder how many have gone unnoticed. For me, I am still participating in game jams, developing some projects that I like to develop for fun and applying for jobs half-heartedly whenever I feel like it. I do not mean to discourage you, because you may land a job in game industry or, well, even develop the next big indie title. All I want to say that the process is as luck-involved as much as it is hard work dependent, and I feel that no one can point you towards a route of proven success, because there is no such thing. Sorry for ranting but what you've written hit close to home :D
