These things exist, but are quite uncommon compared with poorly vented stoves, or people who have a vent for their stove but don’t run the fan at the necessary high power
Thing is that they also are going to burn far more gas than is a stove unless you’re in a really warm climate.
I don’t think that they’re permitted to be built into new-build stuff in California, but they’re definitely grandfathered in in old buildings, and I’ve been in many that have them.
In fact, according to a paper from the Journal of the Air & Waste Management Association, nearly 23 million consumers use vent-free gas heating products.
In 2023, there were 131.43 million households in the United States.
That’d be a 17.5% marketshare for gas heating, and a 38% marketshare for gas stoves, but the gas heaters are also going to use a lot more gas than gas stoves do. I’d be pretty comfortable saying that a gas heater will average considerably more than twice as much gas as a stove.
You can definitely get unvented gas heaters in at least some states.

In a world where every home has a stove, 23 million across the US is uncommon, enough so that people don’t even know that they exist.
Most stoves in the US are not gas; it’s not an “all stoves versus a subset of heaters” sort of situation.
