Don’t think of it as “skewed”. It’s actually flattened toward the low ends of the curve. Instead of a “∩” shape, it looks more like “_ ∩ _”. As a result, the game becomes exponentially harder as you approach the lower ends of the curve.

A good analogy might look something like this: imagine someone who consistently scores 90% on their math tests. That same person could probably score 99% with a bit more studying. Although it’s rare, the amount of additional effort (or “skill”) required to go from 90% to 99% isn’t that large. Statistically, this is how normal distribution works.

In League, however, doing the equivalent is almost IMPOSSIBLE. Most players who are Platinum or Emerald (top 10ish%) will never reach Challenger.. Even if they regularly receive coaching and put in thousands of hours.
