Divisibility

Read this from Manhattan on the first page of Chapter-11 (Number Properties)

In a DS question, there is a statement:
x,y, and z are all NOT divisible by 4.

Shall we interpret the meaning as:

NOT ALL - any from 0 to (n-1) inclusive i.e., here maximum 2 number can be divisible by 4
NOT ALL - none - 0 i.e., none of x,y and z is divisible by 4

Manhattan went ahead with the second interpretation. Need help from experts as First looks more logical to me :(

Infact i did not understand the FIRST SENTENCE
and my mind instantly went to second statement.....

The actual meaning is X is NOT divisible by 4, Y is NOT divisible by 4 and Z is NOT divisible by 4
