I would have to say that is completely wrong unless the parents frequent short tracks. But most kids will see their first race on TV (nascar or indycar). If they show interest parents may then take them to a Nascar or Indycar race then possibly a dirt track if they are lucky. Take a poll of all kids under 18 and see where they first witnessed racing 75% will tell you Nascar or Indycar. And 25% will respond with "sprint cars are go-kart things, right?".
