I went through this and switched from web dev to being a graphics programmer at a game studio

Personally I think LearnOpenGL is still the best tutorial series if you want to work on game rendering engines

Just because it covers a ton of different topics from beginner up to advanced all in one series. You go from scratch all the way up to implementing deferred rendering and a full PBR implementation

If you understand all of those tutorials you have a pretty good baseline for how modern game rendering works (minus ray tracing)

In terms of getting a job though the modern APIs are highly desirable
