Whereas != is commonly used in programming as “not equal to”.
So the mathematician see two factorial equals two, which is true.
The programmer sees two is not equal to two, which is not true.

2 != 2
But what if it’s true? Perhaps the 2 on the left is integer and the right one is character.

Or it’s a language where each number is a different instance, and
!=
compares addresses.
