List comprehension for finding all prime numbers from a range of numbers?

[x for x in range(1,100) if all(x%y for y in range(2,x))]

Not able to understand how above code is returning correct results, Instead it should be

[x for x in range(1,100) if all(x%y!=0 for y in range(2,x))]

The reason is if all is True if only one of the condition is True.

Non-zero integers are considered truthy in a boolean context, so the code snippets are equivalent.

Note that this algorithm incorrectly classifies 1 as a prime number.
