Not just hard things, but much harder than they've done before.
Note that Booster appears to be coming along pretty well. But Ship, which has a much, much more difficult mission profile than Falcon 9, is really struggling, because going to orbit and back is far more difficult than going most of the way to orbit and back. (Please forgive the abstraction - I don't have the relative numbers at hand.)
Hard things fail from time to time. When you aim for something really at the edge of human enginuity, it might work or it might not, and if it works, it will probably still be a close call.
But somehow years ago already SpaceX and it's followers convinced everyone that Starship will definitely happen. And it still might, but if it does, I still think it will be a rocky road.
I would say SpaceX has been extraordinarily lucky for years (not in the sense that they fluked it, but rather that they achieved so much and made it look easy), and this is just reversion to the mean.
