My understanding is that it was profitable if you got the aircraft for free and already had pilots capable of flying them.
If the Concorde had been an actual financial success they would have developed it further and made a successor. And if BA and Air France had thought that the Concorde would continue making them money they wouldn't have retired it after one tragic accident in 30 years of operation. The 737 Max is still being made after much worse.
