Clays are the source of many of the chemical and physical properties of soils that make them a useful medium for the growth of plants and for the less common uses such as a medium for the disposal of wastes. Clays contribute to the formation of soil structure by undergoing seasonal shrinking and swelling.
What is the importance of clay?
Clay is an important part of soil because it contains nutrients that are essential to plant growth. Another way to use clay is through sculpting. One property of clay is plasticity. This means that you can stretch out the clay without it breaking or tearing.

The short answer is, no it should not get wet. Air-Dry Clay absorbs moisture and will become soft again when it comes into contact with water. That is why Air-Dry Clay should be sealed once the sculpture is done and Air-Dry Clay should be stored in airtight containers when it is not used.
