Once your rating is non-provisional, it never goes down if you win, you just won't gain many, if any points if you play a much lower rated player.
This has also been addressed in the Help forum very recently. If you have questions, it's always a good idea to have a look in the FAQ and the Help forum first, and then post in the Help forum if you still can't find the answer.
