Whats better Wrestling or Kungfu?

So i went on youtube and did a little searching and found that wrestlers all beat the kung fu guys. I thought that kung fu and karate all beat wreslting but appaerently no. In every fight i saw the wrestler just ran in and wrestled the guy down to the ground. Some people say a good kungfu-ist will always beat a wrestler but from what ive seen thats not true. Can anyone tell me why a wrestler always beats kunfu-ists karate people and other martial arts people?
