When statisticians say "distribution", do they mean a frequency distribution, a probability distribution, or a plain old list of values?

I find the usage of this term very confusing. It looks like they do most often mean a frequency distribution, but almost none of the material I read or watch makes that clear at *any* point.

Typically probability distribution, but the context should make it clear.  Note you can easily convert a frequency distribution to a probability distribution by dividing all of the frequencies by the sum.
