@FreshJR I understand ping but not ping sensitive traffic.
It's very closely related. Let's put QOS aside, and see examples of ping sensitivity.
Ping is
a duration that describes how long it takes data to get from point A to point B
Bandwidth
is a rate that describes how much you can get from point A to point B
Lets say we have two freight options. (Air and Train)
The trip is 3000 miles with either option.
Speed limit is 600mph for planes & 30 mph for trains.
The plane can hold 50 packages.
The train can hold 100,000 packages.
In this example:
Air: Transport = 5 hours, Capacity = 50 packages
**We effectively have 10 packages per hour with a 5 hour delay for our first package
Train: Transport= 100 hours, Capacity = 100,000 packages
**We effectively have 1000 packages per hour with a 100 hour delay for our first package.

Which would you rather have? Answer is, that it depends.
If you are trying to send a short/urgent message, you want to minimize arrival time (ping sensitive).
If you are trying to maximize throughput, you want to maximize packages per hour (bandwidth sensitive).

Go back into the example, and change "hour" into "milliseconds".
If you are having a phone call / playing a video game, and had the above choices, you would want your voice/bullet to get to the other side within the 5ms option.
If you are watching a video, you would want the 1000mbps option, even though it means you have the wait 100ms to start watching the video after clicking play.
Even though both connections have their own merits, if you reverse the applications, they are useless.
Simply put, video streaming is NOT ping-sensitive.
After the video initially starts playing, it doesn't matter if the ping is 1second or 10 seconds, since as long as the bandwidth remains higher than the bandwidth of the video stream, the video will continue playing and not get stuck no matter your connections ping stability throughout the stream.
