400 Starlink satellites per Starship launch costing $2M is $5,000 per satellite per launch. Basically nothing compared to the eventual mass-produced cost to make each satellite which might be $100,000.
Musk recently said that they need to get Starship working because the launch cost on Falcon 9 is already exceeding the cost of the launched Starlink satellites. With a launch cost of approximately $30M and 60 satellites, they are already at $500k per satellite at most.
