"Mary likes John", or more exactly a tuple (Mary, John) in a relation called "Likes", could be interpreted by the users as "the moon is made of green cheese" if they want.
Just as the tuple (Bill, 0) can be perfectly well be interpreted not as "Bill is 0 years old", but as "Bill's age is unknown". It could even be interpreted as "Bill's age is 43" if you really wanted.
