"Lucked out" or "luck out" has always meant "got or get lucky" here in Jersey. Usually heard in the phrases "looks like he lucked out" or "you might just luck out". "Lucking out' is actually a tad beyond lucky, though...almost undeservedly so. Everyone knows someone who "always lucks out" or "always seems to luck out." Some people just step in good fortune at every turn...others just "step in it." But, come to think of it, "always stepping in shit" can mean lucky, too.
