Yeuh, Obiwan is the shit, but he strait-up lied to Han Solo. "In my experience there's no such thing as luck", luck followed him his entire life:
Killing Maul
Fending off Jango
Surviving the Geonosian Arena
Killing Grevious
Surving the fall on Utapau
Surviving on Tatooine for 20 years...
....shit, he's a cocky bastard
