Most things have three states, the three states of matter. They are solids, liquids, and gas. (In another posting, I covered the fourth, plasma.) Water is one of those whose difference between its freezing temperature and its boiling temperature is within the limits easily reached by most of us and we have all been able to witness its three states; solid (ice), liquid (water) and gas (steam). Although steam is invisible, we see the water vapor formed as steam cools.
In the picture above, the steam leaving the holes in the iron is invisible, but further out as it cools, it forms the water vapor that can be easily seen. So, now you know the difference between steam and water vapor droplets, what good it will do you, I have no idea, but please try to enjoy yourselves and have a great day, you hear?
