With regard to your question, "Am i missing something?" Well, yes. Most of my flying is done in the United States and at many large commercial airports, some, if not all, of the runways are grooved. This allows water to be channeled off the actual surface of the runway. I don't know if airports outside of the U.S. have grooved runways as well--other A.net members will follow this response with additional information on airports outside of the United States.
The grooved runways are effective to the point that for some aircraft and/or operators, there may have provisions in the aircraft performance manuals such that even if it is raining, a grooved runway may be considered "dry" for landing and/or rejected takeoff operations.
Of course, even with a grooved runway you have to use some judgment and common sense. It is important to remember that the touchdown zone of the runway (first/last 3,000 feet depending which way you are looking)--the portion with a lot of rubber deposits from landing aircraft--can deteriorate to the point of being considered "icy" when it is actually just wet.
So, grooved runways help reduce the propensity of an aircraft to hydroplane, but they do not eliminate it.
Lot of variables.
