2 is one of the nine ordinary outcomes of digit reduction, sitting comfortably inside the standard 1–9 range every mainstream school recognizes. There's nothing unusual about landing on it.
What makes 2 worth a dedicated explainer is its neighbor: 11 reduces, digit by digit, to 1 + 1 = 2 — but most Western schools stop before that last step and keep 11 as a master number instead. So two people can both do "the math that leads to 2" and end up with different final answers, depending only on whether their birth date happened to produce an 11 along the way.
