It was very surprising to see they have no matching segment at all. At gedmatch, after lowering the threshold to 1cM-100snps, their largest matching segment on X was 3.2cM-288snps. Total X match 16.8cMs.  Does this seem unusual, and does that mean my son's X-matches are all from my dad's side? My son and I share 196.1cM on the X.

A mother-child will always share a full X-chromosome. The 196.1cM is the size of the X-chromosome using Build 36 standard and the 182cM is using the Build 37 Standard.
