They will creak and make motor noises that sends the owner in to fix it mode long before.
They simply have too many teeth engaged at any time to slip.
You will feel a worn ring with a new chain many thousands of km before it would skip.
I have never actually seen a worn chain ring skip, shitty running has driven the owner to replace long before.
Generally it is the cassette that will skip, so I would be checking for tight links.
A worn chain ring will absolutely cause a chain to ship if you put high force into the pedals. You'll most likely notice it when sprinting or drilling it up a hill, and if it's bad enough, from a stop, when you put that initial torque into the chain it can and will ship. I've been going through a big ring about once every two years since focusing solely on riding and that's with regularly changing chains and cassettes. And honestly, I never noticed any issues with the rings or how the bike rode up until the point where it started shipping.
I am however a bit surprised that you're shipping it on the little ring too. I've never worn out one of those and you generally aren't putting through the kind of torque/force when in the little ring. So while I would say yes, consider it a worn ring, the fact that it's skipping in both seems odd. But if you've replaced both the chain and the cassette, the ring is the next logical step.
