I think you're splitting hairs here. Not sure what definition or context of determinism you are using, but in most scientific fields not only is probability the de-facto example of non-determinism, but in fact the words are often used interchangeably.

By definition, if your outcome is a random draw from a probability distribution (known or unknown), you cannot guarantee the outcome in a deterministic manner; you can only guarantee that in the limit, a large number of random draws will follow that distribution (known or unknown). But that's not what one would typically call determinism.
