That's what Musk wants you to believe.
In reality, reusability was the Achilles heel of the space shuttle, due to the thermal insulator tiles that could be easily damaged during reentry, so they had to be rechecked rigorously before the next flight, and the damaged tiles replaced. We haven't seen any of that - so far only the booster was reused, somewhat, as in 2 were reused, with one failure and one success, but only much later.
And then there is the orbital refueling, but that is so far in the future that it's not even worth discussing.
