Lottery luck, or is it no such thing as luck.

Suppose first that, of a thousand people facing death, only one can be rescued. If there is a lottery
 to pick this one survivor, and I win, I would be 'very lucky. 
Simply. someone had to win, and why not me?  There is nothing here that needs to be explained. i.e there was no luck involved.
Being lucky or unlucky is an aspect of language that belongs in medieval lore.
