What Would Bierce's Devil's Dictionary say? Perhaps something like:
Luck: that name given to certain outcomes coincident with a blend of ignorance of statistical variation and superstition. It has the virtue of being brief.

Chance: acknowledgement of statistical variation, without the baggage of superstition that luck has.
(Intended as all in good fun. http://www.thedevilsdictionary.com/c.html doesn't include chance or luck)
