True, but also the commandments aren't actually numbered. IIRC, there are 13 "Shalls" and "Shall nots". So Catholics lump that section in with the first (no other gods, etc.) while the Protestants make room by joining "don't covet wife/property". There's arguments to support both sides when looking at the historical context but on that specific issue I'd lean toward the Catholic interpretation making more sense considering god is telling people to make statues shortly after (Exodus 25:18). Either way it's silly to be arguing over rules that bronze age people invented.
