I mean... it doesn't have to be, though my experience is only from fflogs and not like a speedrun leaderboard or anything professional.
Getting rank1 means that you were the best in the world, by some metric, for some amount of time, under certain conditions and support factors. You can feel proud of it in a normal way without making it your entire identity.
Also i'm good friends with pretty much everyone who could conceivably compete for the top placements and none of us would be heartbroken to see that a new record had been achieved. I think this is a pretty common dynamic, at least in competitive fields where there is an objective measure of success (rather than something adversarial).
You can tell by the direction it's written, like つ=ツ because the strokes go horizontally left to right like the hiragana, while し=シ because the strokes go down vertically first. If that makes sense
