Wrong!
Surgeons wear masks to protect the patient on the table. Ordinarily the various microorganisms in exhaled breath are not dangerous to others. But during surgery the body cavity is opened and vital organs that would normally be protected by the skin are open to outside infections which they can't fight off.
In the case of Covid-19 the idea is to contain the virus to persons who already have it, albeit they may be only carriers. There is some protection afforded the wearer but this is secondary.
