Yes, but that’s because that’s the way your mind interpreted it, it could have just as easily thought that the arrow (little side) should point in the forward direction from left to right, so ‘point to the bigger number’.

Basically two completely unrelated things both make sense to you in the same direction, and that happened to be the direction that the the people picking the symbols also picked. If they had simply picked the opposite direction, all the people who currently struggle might find out perfectly natural and be confused as to why ‘you’ have such a problem understanding it.
