They do. Numerology is more important in the Aurbis than it is in our universe, and nine is one of those key numbers. Many of them have multiple instances which can be attributed to them. The Ayleids, for example, obsessed over the number eight. In the Sermons, where much of the numerology is layed out, the number nine represents 'The Missing' which, while an obvious reference to Lorkhan, some view as also representing mortality (as missing divinity). The idea has more credence considering nine is paired with eleven in Sermon 29, the Number of the Master (the Ruling King) linking both mortals and Lorkhan, and a number important to the enantiomorph (which is also part of Reaching Heaven by Violence), as Vivec wrote:

"Hortator and Sharmat, one and one, eleven, an inelegant number. Which of the ones is the more important? Could you ever tell if they switched places? I can and that is why you will need me."

Looking at both occurences in the lore when these numbers pop up and the 36 Lesson of Vivec should be a good way to help unravel the significance of some numbers.
