We would only say "we got lucky with our universe" if we already presume the existence of other random universes. If there's only one universe that was purposefully created, then luck had nothing to do with it. So the equivalence you're trying to draw is more of an opposite. Saying "our universe was done on purpose" is the opposite of saying "we got lucky with this universe," in much the same way that carefully placing 4 coins heads-up on a table is the opposite of flipping the same coin 4 times. Once you're willing to entertain gods as an explanation, then no other explanation is needed, or will suffice. You don't need to go so far as elementary physics before considering a god. You can just look around and say "a god created this one second ago, including our memories." From the other perspective, if you want to consider the idea of a god scientifically, then the obvious question is, where did the god come from? If they were powerful enough to purposefully create our universe, then they must have REALLY gotten lucky to have evolved that way in their own universe, right?
