The fact that they have had some form of training could be cause/effect: they are stage performers so elrmentary training is perhaps part & parcel of that. A singer must have some sort of musical timing (although with some of today's crop that could be questionable) so it is also reasonable to suggest that they also have an understanding of body rhythm.
And when it comes down to it, most celebs have some sort of advantage in one area or another, it's just that those advantages tend to even out:
Actors can "act" the mood of the dance, they can more easily be specific characters
Sports people have stamina and that competitive spirit
Comedians are used to performing in front of an audience which might be less than receptive to their efforts (for audience read "judges")
Presenters/news readers are likely to suffer less from nerves should things go wrong, and are used to things being "live"
Models should have a grace and a posture and be able to carry off different moods
Some contestants might have combinations of the above to a greater or lesser degree.
