My fun anecdote...
Some of Valorant's game servers are hosted in a data center very close to my house. When I played, my ping was in the single digit milliseconds. Some people accused me of being a Riot employee.
Of course, that low ping didn't prevent me from being utter trash. My K/D ratio was usually around 0.3.
Come to think of it, seeing the network buffering they perform, I wonder if having such low ping actually gave me a disadvantage when peeking towards someone with a 30 ms ping?
