My teacher claims that in the Pythagorean Theorem y always is equal to x, unless z is less than 2. Is this true? It goes completely against what the textbook says.

The Pythagorean Theorem says that the sum of the squares of both legs of a right triangle equals the square of the hypoteneuse......

So

x2 + y2 = z2      where x, y are the legs and z is the hypoteneuse.......x and y aren't necessarily the same.....and z has to be less than the sum of x and y (by the Triangle Inequality)
