Pretty much. Or more precisely, if you try to start it after the free period passes, steam will attempt to authenticate that you own the game, realize that you don't, and refuse to start the game. 

I don't think it deletes the data, mind - after all, it's in their best interest to make it as easy as possible for you to decide to buy the game - but until and unless you actually buy the game it's just taking up several gigabytes of space on your hard drive.

How do time limited games work on Steam
Is there a way to get to know how many external tasks (console applications) is reading queue?

I am using Service Broker external activator.

What i want is something similar to information i get from sys.dm_broker_activated_tasks, just for external queue readers.
