When in a problem, two integers are given as x and y, persay, can we assume they are of different value?

Reason being, I thought I always could. Then I ran into a challenge problem, where you cant make this assumption:

X and Y are prime integers. What is absvalue (x - y)?

If they are the same prime, |(x-y)| = 0
If they are different primes |(x-y)| could take on different values depending on x and y.

You cannot make the assumption that X and Y are different integers. So X-Y can equal zero.
