Ok, so first of all, a PING is the lowest form of communication. It's ok to use to see if you are getting somewhere, but it's not nearly as useful in troubleshooting problems. The reason is, BECAUSE it's the lowest form of communication, it's the one that routers pay the least amount of attention to. The routers handle all of their priority communications first, THEN respond to ping requests.
That being said, your pings on the Cox network, appear to be less than 20ms, (That's 20 thousandths of a second), but the LAST one to google was 160 ms. (A little faster than 1/5th of a second). Not nearly as fast as Cox's routers, but still, not a long wait.
Again, remember, Google's response take place after it's priority data.
Another thing to remember, once your data leaves Cox's network, and reaches the internet proper, Cox has no bearing on the route it takes, and depending on the router, and the amount of internet traffic, as well as however busy the game server is, it can take a toll on gaming. Find out if your game has other servers you can connect to.
