ELI5: Why were older game discs able to be put into the system and instantly played, when now you have to download the entire game first?

Because the older games had the entire game stored on the disc, and now there is only a part of it on the disc and the rest has to be downloaded. It allows them to make games bigger, more complex AI, better graphics, and the backbone of the games more complex than a single disc could hold, but also allows for updates to bugs in the code.
