Yes, I've seen the numbers, though I don't have them at hand any more. Obviously many Argentines care about soccer, many of them fanatically and even criminally so, but for the majority it's simply not important. The same is true of American football, baseball, basketball, golf, tennis and every other sport, not to mention cultural activities like movies, theater and dance. They are all minority pastimes.
That's a half-truth. The Argentines who care it about are literal psychopaths, but most Argentines ignore it or actively dislike it (because of those psychos).
