I believe instead of "deterministic" you could use "consistent" or "always the same": the order doesn't change with time and is the same from one run to the next. Not everything inside a computer can be said to behave this way: for instance processes which change with absolute time, with durations or with user or device input. Or processes that have been made to depend on the above factors intentionally to avoid predictable behavior (as in the original security hole).
Python never guaranteed an order

In theory, /dev/random is non-deterministic because it uses sources of entropy whose internal state is (for practical purposes) impossible to know well enough to make any predictions.
