The store owner has already sold 32 ice cream cones. Each of the three families plans to buy 4 ice cream cones, so they will buy a total of 3 * 4 = <<3*4=12>>12 ice cream cones.
Therefore, the total number of ice cream cones sold after the three families buy their ice creams is 32 + 12 = <<32+12=44>>44.
Since the store owner thinks the total number of ice cream cones sold for the day will be about 20, he is not correct.
