What does it mean when humidity is 100? (link)

It just means that the air is holding as much moisture as it can at a given temperature, in the form of water vapor, which is an invisible gas. However, near 100% relative humidity, you can get water vapor condensing into very small water droplets to form clouds, including fog near the surface.

Must it be raining when the humidity reaches 100%?
