What is the difference between realm, room and overworld?.

So, a room is similar to a realm, but they have to have a door that goes into another room/realm, by which you access them.
A realm is the same thing as a room, but it does not have to be connected to another room/realm, it has a name that you can search to access it, or you could put it in an overworld.
An overworld is a kinda similar to a realm, they are 99x99, but you can only build 20 blocks high, and there are only certain blocks which you can use in an overworld, which have a little blue highlight at the bottom when they're in your inventory. You can place realm spots in overworlds, and when you use a realm deed on them, you make a castle which when you jump in it puts you into that realm.
I saw it as explained this way: if a realm is a building, then an overworld is a city
because you put the realms in the overworld.
Does that make sense?
