We know how much SLS cost in a lot of detail. Also remember, SLS development, the 20 billion is only to first launch to get to 1B they will likely drop another 10 billion or so and it will likely take until 2030.
We don't know about Starship, but it is far, far less. SpaceX could absolutly not spend 5 billion $ a year on the program.
And the complexity of Starship is in a different dimension.
So Starship for a fact is orders of magnitude cheaper then SLS and orders of magnitude more complex.
