I guess it is the same as taking a multiple-choice test, filling it out randomly and getting a perfect score.

Yes, you are lucky. But also: you should feel guilty about it.

Same with random things happening in your life and turning out well. If you don't know why they happened then who says you will be lucky the next time? Better feel a little guilty and try to understand how you can turn the odds your way (and perhaps also so others can benefit).
