There’s ones that use evaporative cooling, meaning they draw water off of a river/lake/creek (or domestic water supply) and cool through putting that water into the air. Lots of power plants do this exact thing, especially nuclear power plants. There’s ones that use closed cycle cooling, like a bigass water cooled PC. The water generally stays inside. It periodically needs to be cycled. There’s also measures out there that account for all of the water needed to produce all of the components. The water used for that is one time usage. Are these things “using up” water? Sure, some of them are in the sense they are accelerating evaporation. Some are using very little water.
