ELI5: Why isn't a one second video at 24 fps 24x the file size of a picture?

Example: If one photo is one megabyte, why isn't a one second video at 24 fps, which has 24 photos in one second, 24 megabytes?

I get that it's to do with compression, but how could you compress that without losing too much quality and pixels? Pls explain.

Video compression uses the fact that consecutive frames tend to be similar to each other. Instead of storing each frame separately, the file only stores the differences between the frames (except for some frames known as "key frames" which are stored in full), which takes up much less space.
