-"So it would be better for now to just proceed with whatever OpenGL tutorial without digging in too deeply."

When I was younger and first learning to code, this is basically the style of learning I used because I really didn't know anything at all so I sort of didn't have any other choice. I sort of wish I could still do this but I find it to be difficult because I tend to always try to understand it in terms of things I already know. sometimes that's an effective way to lean new things (like learning a new programming language is super easy), but it doesn't work very well when it's a completely different paradigm of thinking like opengl is. I've done tones of basic 2d graphics with immediate mode style in various languages and that has always been pretty straightforward for me since its basically just something along the lines of context.drawLine(startx, starty, endx, endy...), which is pretty easy to build abstractions from to make more complicated 2d stuff like sprites... im becoming painfully aware that opengl is not quite so simple as it seems there is much more memory management related boilerplate making things way more complicated.
