NASA I believe gets a certain number of slots and will be giving up an astronaut slot for each of these tourist flights. When Dragon and Starliner finally start flying though they'll be able to increase the number of people able to be on the station at once so net they're probably no worse off than before. Currently only 6 people (up to 9 but only briefly during a handover) can be on board at once because each Soyuz can only carry 3 people. Crew Dragon can hold up to 7 but most of the time will be flying with less, iirc 3-4.
