As Omar said, the Fundamentals course is great to get up to speed on those. But really, like everything in blender, it just takes some time. When I started the courses I felt like there was a lot I wasn’t understanding on the technical end (there still is, im far from experienced). But the more and more courses you do, the more repetition of a lot key elements like shading and geo nodes become easier to understand. Keep it up, you learn more every day!
