Steam is water in its gaseous state. It's invisible.
Dry saturated steam is water in its gaseous state at its boiling point at the prevailing pressure. It's invisible.
Superheated steam is water in its gaseous state ABOVE its boiling point at the prevailing pressure. It's invisible.
Water vapour is water in its gaseous state, by convention BELOW its boiling point at the prevailing pressure. It's invisible.
Water is visible only in the solid state (ice) or the liquid state. If you can see it, it's liquid. If it's finely dispersed as an aerosol, that's still droplets of LIQUID water suspended in air.
My Goretex coat lets water vapour out, but doesn't let liquid water in.
