As long as they throw away the rocket on each launch, that seems really unlikely. Starship at scale will be down to the cost of fuel and ground services, with just a tiny amount amortized for the rocket itself.
Even Falcon, with only the first stage reused a dozen times or so, is cheaper than anyone else launching today. With cleaner-burning fuel, Starship will be good for hundreds of launches on both stages, with fast turnaround. (And Stoke Space is attempting that too.)
