Maybe things have changed. But when I was in highschool in America in the early 00s, statistics was an optional math class offered to juniors. Nobody had taken stats before reaching highschool, which is what the GP calls for, and kids in the "artistic track" weren't required to take stats at all.
I've unironically thought the same thing as the top post. Unless you're going into STEM you probably don't need more than the most basic conceptual understanding of calc or trig. But understanding how probabilities work is a huge benefit in every day life.
Perhaps GP is not from the US. In the UK, statistics is not separate to mathematics, and is first met in primary school (even in three-school areas more analogue to the US) getting progressively more advanced up to and through (compulsorily until sixth form - the two years prior to university) 'high school'.
