ELI5: If water is wet, how does hot water dry out your skin?

While the explanation would involve skin oils, does this apply to cold water too?

Your skin is protected by a layer of oil that you produce.  When you wash the skin, especially with hot soapy water you remove this protective layer or oil.  This then allows your skin to dry out more easily than if the protective layer was there.
