A ping doesn’t tell much useful information. The most it can tell you is that pings can successfully travel the route. If ping fails, it doesn’t mean that the route doesn’t work — it only tells you that ping doesn’t work along that route — and routes often deliberately block pings.
Ping is just a trivial initial test. The result is useful when the the remote device is in the same network and you know the characteristics of all devices along the route. Otherwise, it doesn’t tell us anything unless it works.
For more useful information, try TRACEROUTE instead of PING. Although some of the technology is similar, the information is much more detailed and useful.
