They don't have fully reusable rockets in production yet. They just reuse the first stage. Even with that alone, they are the cheapest launch provider by a significant margin, which is why they've captured such a large share of the market.

At this point it seems pretty plausible that if they succeed in making a whole rocket reusable at a decent cadence, instead of throwing away an upper stage with each launch, then costs will drop dramatically.

Thier losses decreased so yes. They are launching at an unbelievably cheap price compared to anyone else on the planet.

They are still heavily investing in starship and starling though so that is a large pot of why they are running at a loss
