No, not at all. If somebody is following the Eatwell plate sort of regime with 1/3 of calories coming from carbs that could easily be 800 cals to 900 cals worth of carbs per day. They say that as a rough guide 1 gm of carbohydrate (and protein) is about 4 calories, so easily at least 200gms. When I was eating carbs, 2 slices bread for breakfast, 2 bread rolls for lunch and one baked potato for dinner, that was 700 cals so just less than 200 gms, getting up to 240 would have been easy just by adding one slice of toast.
