I mean, Google Ngrams is written language so slower than the spoken one. The point is more that Spanish < Italian.

But if your mom or who ever telling you this is a greater authority than a company analyzing data with no agenda in this case, than that’s ok too. But maybe I’m misreading the graphs. The Italian one has kind of a peak in 1921 but a bigger one in 1814. It only goes above those random peaks around 2000 in Italian and Spanish looks less random to me before that.
