Steam is water in a gaseous form and invisible.
Water vapor is made up of water droplets that are so light they are carried by the air currents.

Steam is water vapor; water vapor is not steam. A square is a rectangle; a rectangle is not a square. Both are parallelagrams; but a parallelagram isn't a square or a rectangle. A thumb is a finger but a finger is not a thumb. Things are just like that sometimes.
