Learning about themes

Hey! I’ve been watching other tarot readers on YouTube and instagram(I realize the readings themselves aren’t accurate) but I started to pick up on things they say like “four major arcana cards, that means feelings are intense” or “the whole spread is cups, it’s emotional”

I’ve also seen people talk about how certain cards when paired together have specific meanings. For example while doing a future spread I pulled both the king and queen of pentacles.

Are there resources to learn more about over arching themes and how they relate to the cards?
