But I’ve never mentioned median. I’m stating that by definition, 50% of $ outperforms SP500. Sure that could be skewed, with a median underperforming, where in the extreme 1 participant has $20T outperforming and the other 1,000 collectively have $20T underperforming. But on average your $ has a 50/50 chance of under or over performing total market (and thus basically SP500) by throwing darts at a board.

But you mentioned average (mean). You can have the same average but different median, and only if you would talk about median it would be guaranteed that 50% of the cases are above and 50% under.
In the case you mentioned, with an average, there might be extreme outliers that make the average different from the median, thus rendering the assertion that 50% of the cases are above the average and 50% under false.
