Being a good programmer helps though, technical challenging things tend to have much smaller and worse competition.
Like, you probably wont make a lot of money making another 2d platformer no matter how well you code, they are so easy to make that there are millions of them out there already. However if you make a performant and bug free factorio or minecraft clone you will at least get a few thousand people try it and from there it would grow if it is fun.
