Theres a few different kinds. There are rv parks, built for both long term living and temp camping usage with full hookups. These are found anywhere, even the smallest of small towns usually has one. These always have a person, they are private businesses.
Then there are various public (state county federal etc) campgrounds that vary widely between amenities and staff and cost. There are plenty that are full rv parks with hookups, and plenty that have nothing but pull through space and a picnic table and grill and a bathroom. Many are on dirt roads and many are not even RV accessible and people just camp out of cars and trucks.
Some have people in a booth charging at the entrance, some require online reservations, many are first come first serve and have a self-pay system, many are free. Many have differing prices for a site with hookups or just tent pad or a walk-in site.
Some have volunteer or paid camp hosts who basically take care of the place for the season in exhange for living there in an rv, many have no staff except for those from whatever land management office that come through as part of patrolling or working in that office's lands. The ones in big national parks and state parks and things often have dedicated campground ranger type workers running things. There are also often campfire evening programs put on for the campers by interp rangers at these parks.
