The number 3 (and as you can see there are 3 of them), is the number of creation/destruction. 3 goes into 9 3 times, obviously, and 9 is the number of permanence, in terms of endings, and is like its own specific power number (or as I call it, a power-power number) and is forceful. As said, you might want to see if it is merely a coincidence or if it has any significance and meaning to you at all.
