No, two of them are the same, but one is different. The "all As are not Bs" would read like "if A, then not B, If B, then not A" and the "No As are Bs" would read the same way as well. The other statement, "Not all As are B" would read "There can be an A that is not a B." What this really means is, say you have 100 total As and make the Not All As are B statement, This means there has to be at least one A that is not a B. The easier way to read it would be Some As are not B. There are a few SA and MBT questions that prey on this distinction, and those are usually the harder ones.
