No it doesn't. It shows, as the OP says, persistent low level packet loss, and even at the level showing that's enough to create intermittent but severe speed problems and an unreliable connection. I can say for a fact as my own connection was doing this for three of the last four weeks, and in the example below was glitching on work videocalls, dropping out on streaming, with poor and erratic speeds in the 50-90 Mbps range. I'd also point up that the OP has worse and more inconsistent latency than my own shonky connection, so how you judge that a "good service" I have no idea.
Packet loss is often immaterial for casual, non-time sensitive use (general web browsing, Youtube cat videos, social media), but for all other uses for which speed or latency matter, even the very lowest levels of packet loss are a real problem.
