I've seen similaer videos in the pre AI time where someone stiches stock fotos together that fit to the lyrics. Absolute shit, and this is the advanced way to do that. It's a costly gimmic for illegal youtube uploads. The videos have no more value than that. So yes, you could do that in half an hour with your current knowledge and 0$, but it would be meaningless still images instead of meaningless video snippets. I see not much difference.
