Fluid probability is not the same as item probability description:
https://lua-api.factorio.com/1.1.101/ty ... robability
https://lua-api.factorio.com/1.1.101/ty ... robability

I assume they work the same?

Yep! I copied the probability description to FluidProductPrototype for 1.1.102. Thank you for originally adding the description on ItemProductPrototype on the wiki.
