There can sometimes be some confusion around the Room terminology.
A Zoom Meeting can have Breakout Rooms - and also a Waiting Room.
Breakout Rooms are sub-sessions within a main Zoom Meeting.
A "Waiting Room" is an area for participants to wait before being admitted to the meeting - if so configured - but it does not have meeting-features.
A "Zoom Room" is something different. It is a separate hardware/software solution (typically intended for use in physical conference rooms) that is used to attend or Host a Zoom Meeting. This is a separate licensed product from Zoom .
Zoom "For Home" devices (also known as personal collaboration devices) can effectively be used as "Zoom Room" - which means they can be used as a place to join or Host a Zoom Meeting.
Confusingly, there is now also another variation: "Room for Zoom". This is a modular personal meeting space made by Room.com with an integrated Zoom Room.
Hope this helps clarify the Room terminology.
