And as for measuring luck, it's actually quantifiable. Here's an example. Suppose I'm a card counter in blackjack with an expected profit of $10 per hour. I go to a casino and win $300 in 3 hours. I "earned" $30 and I had $270 of good luck. The next night, I lose $200 in 5 hours. I earned $50 and had $250 of bad luck. Luck here is the difference between your mathematical average result and your actual result.
