How is it that videos or music tracks, that are the same quality ant length, can have different file sizes?

It depends on how much compression you can get out.
If I have an hour long video of a black screen, I can perform a lot more compression than some other videos.
There is also a different acceptable amount of loss. Just because a video is 4k necessarily means that every pixel was preserved perfectly. You could have algorithms that are 99% effective in rendering the original from the compressed data, but take 1/10th the space, so it’s a loss you’re willing to take.
