“They make suppressors for revolvers? I did not know that.”
Not really no, there’s a lot of mockery going on here about stupid people in Hollywood that think you can attach a suppressor to a revolver and actually have it work - physics don’t work like that, there’s a little thing called a cylinder gap that turns that into an inane exercise in futility. Or turns fingers into sausage meat if you let them get too close to the gap during firing.
The only revolver I’m aware of off the top of my head that CAN be silenced is a pretty unique weapon called the Nagant. It has a pretty novel design that levers the cylinder up against the forcing cone when firing, effectively eliminating the cylinder gap. Not exactly a practical system, mind you, the trigger pull is god awful as a result.
As mentioned, laws against suppressors are about as dimwitted as outlawing mufflers on lawnmowers because you’re afraid someone could use a silent (HA!) lawnmower to murder someone surreptitiously. Many people though don’t actually know the first thing about guns, or suppressors, and get their warped misinformation from Hollywood writers and directors that happen to know even less about the topics.

The design is “unique”, but the revolver started production in 1895, I believe, so it has been around for quite a while.
