OpenGL is probably not the best way to start game dev. It is a bit too low level for that. I mean, OpenGL is awesome, and a great way to learn graphics programming, but if you intend to make a game that is fun to play, it is easy to get lost in technicalities.
When I started with Blitz Basic, not only my productivity skyrocketed, but I also made better games, because I actually thought about gameplay, not about getting the maths right. Blitz Basic is a game-oriented variant of the Basic programming language, very simple and straightforward. You can try it if you want, but it is two decades old, so I don't know how well it aged. But the important part is to have something simple that can free you from technical details and boilerplate, it can be an engine.
That's unless you want to practice with the technical details, but doing that, the output will probably be more demo than game. And by the way, if you are into that you should check the demoscene, it is awesome.
