Just wanted to second this recommendation. I did the course a few months ago with near-zero baseline in graphics programming (though a few years' experience as a standard swe), and it gave me a pretty decent grasp of how 3d shapes get drawn on the screen. Afterwards I was able to pick up webgpu in a matter of days, which I don't think would've been possible without the understanding I gained from the course.
If anyone's looking for motivation, I made a wasm-compiled demo of the renderer you produce by the end - https://rmshin.github.io/3d-renderer-wasm
