That's correct. The 1/8 and 3/32 refer to the width of the chain. The pitch is the length between the links. The pitch of modern chains is 1/2", doesn't matter if it is a 3/32 or a 1/8 inch chain. So, the 1/8" chain will work fine on a 3/32" chainring. But there is no reason to do this, unless you have a 1/8" cog on the wheel.
