Unique Numbers Check

You are given a list of integers. Your task is to determine whether all numbers in the list are unique. In other words, check if the number of unique elements is equal to the total number of elements.

Formally, let \( A \) be the list provided. You need to verify if $$|A| = |\{x : x \in A\}|.$$

If true, output True; otherwise, output False.
