If you look at it that way then yeah, the Raven Guard successors are not exactly rare, but when viewed from a much broader view point, the Raven Guard bloodline within the current pool of chapters that are operational in the Imperium is really quite rare compared to the numerous successor chapters of the Ultramarines for example. Also, IMO what they meant by rare is that its really hard to make a successor chapter of the Raven Guard because their gene seed has been irreparably damaged, and well, damaged gene seed is not really a good source if one is trying to create a successor chapter.
