Does the Free Unity Come with Premade Tons of trees, or is that Just Pro version?

I only have 1 tree when i go and add a tree. Is that how it’s suppose to be . Cause the Tutorial videos of some guy, he had tons of trees and he said they come with unity

i have 4.1.5 for mac free version

Unity does not come with many trees.

You need to download them for free from the assets store Unity Asset Store - The Best Assets for Game Making

If you want to place some terrain trees - That’s done via the inspector for terrain:

Or you want to create your own trees using the tree creator:
