It’s a scam because as you just pointed out they can only clear the registers and can’t get very far into the ducts.
In most houses ducts have a lot of twists and turns. Some times your ducts will split off from the heavy sheet metal ducts and go down correlated tubes, etc.
It’s damned near impossible to clean the entire ducts and even trying could mean damaging a part of the duct you can’t even access.
The duct cleaners will try to convince you that they can clean every nook and cranny of your hvac system.
They clean like 20% of your ducts and call it good. It’s pointless.
Save the money and clean your own registers with some soap and water. The ducts won’t get cleaned anyway.
