Ummm, well. Not really the case, unless you closely define "small GA market".
If you look at the FAA registry, it includes the model year for the aircraft. In my January 2019 database, there were 295 2017-model Cirruses, vs. 240 Vans aircraft of ALL models. 41 of them were RV-12 light sports. There were only 72 2017 Cessna 172s.
Annual "Production Rates" for individual RV models runs in the 3-5 dozens, not the hundreds (looking just at the US-registered examples). There are lots of RV models, of course, so that does build the numbers a bit more.
Here's a stab at extracting the number of new RVs added to the US registry over the past eight years. It is effected by the FAA re-registration process, but I've tried to compensate for that.

As I said, the above table has compensation for the de-registration process. This table shows the net RV fleet size for individual models, with the net fleet size each year for Cirrus. The number for each table is extracted from that year's registration database; model year isn't used.

I don't include the RV-12 in here because many are SLSA or ELSA. Later RV models aren't here, either, but there are yet low numbers for them.
In any case, there ARE more RVs in the US registry than Cirruses...but the RV series dates back to the 1970s, and the Cirrus just in the past 20 years or less.
