[General] What exactly is luck?

People talk about luck all the time.  But, what exactly is it?  Assuming that it's a real force, how exactly does it work?  Where does it come from?  Is it related to magic?  Why are some people lucky, and others unlucky?

Luck is another name for probability. 

High luck means getting the desired probabilistic result a non-reasonable amount of time.

Low luck means getting the non-desired probabilistic result a non-reasonable amount of time.

All your other questions depend on the universe.
