Sure are. That and ice crystals; all evaporated from water on earth!
All clouds are made of water vapor.
Clouds have to do with water because water vapor precipitates into the clouds.
All clouds are condensing water vapor.
Clouds are visible masses of condensed water droplets or ice crystals floating in the atmosphere, while water vapor is the invisible gaseous form of water that is present in the air. Clouds form when water vapor in the air condenses around particles like dust or salt nuclei.
Liquid water is changed to water vapor by the process of evaporation (or boiling)Water vapor forms into clouds (liquid droplets) by the process of condensation
Soild water
Actually, clouds aren't even water vapor! Water vapor is invisible, and clouds aren't invisible. Clouds are in the liquid form of water, believe it or not. There may be water in solid form if ice is present in the cloud, but otherwise, clouds are fully liquid water.
Fog and clouds are a form of water vapor that can be seen.
Clouds are masses of condensed water vapor, therefore, all clouds are water.

Water Vapor
Yes, water vapor is a key component of clouds. When warm, moist air rises and cools in the atmosphere, the water vapor condenses into tiny droplets around particles like dust or salt. These droplets eventually come together to form clouds.
