You now know enough to be dangerous. You now know enough to be dangerous.
And i hope i have definitively slayed (slewn?) the mythology that module-making is a mystic domain of Drupal druids.

Hooks are magic portals that let any module appear in another part of Drupal and do something.
More technically, a hook is tied to some sort of Drupal event and is an opportunity for our module to take action.
There were 251+ hooks in Drupal 7 core.
After a concerted effort in the development of Drupal 8 to remove hooks and replace them with more modern and widespread (outside Drupal) programming practices such as plugins and services...
There are now 288 hooks in Drupal 8.8.
To be fair, we moved some big contributed modules like Views into Drupal core ... but even after that, we've added 25 hooks to core since Drupal 8.2 (and only deprecated 9, which are removed in Drupal 9). Hooks are still very much a part of Drupal.
Every contributed module can provide hooks, too.
