Gosh everyone's just projecting their feelings onto OP, it's fine to be competitive, it's fine to wonder what the average Osu player is like. Just don't get an unhealthy obsession over standings
However, the average over all accounts may not be a meaningful statistic, as there are so many inactive players of this game. You're certainly above the median too, in terms of pp, with a current standing of #370,036 compared to just under 9 million accounts (like I said, pretty meaningless, right?)
I looked as well for some stats on "active players" (e.g. rankings of monthy active users) but couldn't find any. I also stopped caring like a lot of people here
Then there's what average even means for you. pp? Accuracy? Simply being able to clear harder songs? There are many heuristics for skills, and pp is a rather specific (but standardized) way to judge someone's skills. In addition to skill, doesn't it favor people who go out and download more songs instead of someone who plays the same 10 songs every time? I'm not sure about its inner workings.
