I wouldn't get too excited... the list shows to me that the kids only know about professions they're directly exposed to or repeatedly hear a lot about.
Kinda dumb to ask kids what their ideal profession is when they really only understand about 10 jobs.
This is a pretty poor assumption IMO. This crappy article didn't even bother to list the ages of these "children" (were they 6, or 16?).
Personally, I wanted to be a paleontologist when I was in 2nd grade, but by 6th grade I wanted to be an electrical engineer (which is what I ended up doing in college). I was never really exposed to either of those by anyone I knew, only from reading.
