This is correct from a scientific standpoint.   Air and water are both 
fluids.    The state they are in can vastly affect their properties 
though.   Gaseous fluids are compressible.   Liquid fluids are not (well 
maybe slightly, but not really) compressible.   Both fluids can transfer 
heat, flow through pipes, etc, but the way they do this can be vastly 
different.   Keep that in mind.
