Of course not. Sometimes it's cloudy and there is no precipitation. Other times it might snow, sleet, or hail. The presence of clouds in no way guarantees that it is raining. Conditional claims only work in one direction.
Every conditional claim has one sufficient condition and one necessary condition.
Beyond the grammatical structure of the conditional claim, it is important to evaluate the actual relationship between the clauses. Bill Clinton is president and sometimes the moon is full. Of course not. So even though we can randomly plug independent clauses into conditional claims, it does not mean the conditions are actually sufficient or necessary. Again, one must evaluate the logical structure as well as the truth of the content.
