This is not my understanding.

Bufferbloat is caused by too much buffering in your host, the endpoint, and
all intermediate nodes. As a result, they feed packets into the network
faster than all of the intermediate nodes can pass them on. And then your
latency-sensitive packet gets stuck at the end of those buffers because
nobody across the network honors quality-of-service markings in the packet
or even uses them honestly.
