Nope. It tends to be the succulents with a stem, such as Echeverias or tender Sedums. Generally you won't see aerial roots on Haworthias or Aloes. Also, if you are watering correctly, you likely won't see aerial roots at all.
You are more likely to encounter air roots with succulents that grow quickly and are in their active growing season. For example, Graptoveria ‘Fred Ives' and Graptopetalums grow quite quickly and tend to stretch out easily if they don't get enough light.
