Of couse all the others are odd because otherwise they wouldn't be prime. All primes after three are also not divisible by three... "magic". The only difference is that there are is no word like "even" or "odd" for "divisible by three" or "not divisible by three".

Yep, hence why 2 is unique - there is a word to describe numbers that are divisible by 2, and 2 is the only one of those that is a prime number.
It seems that you don't know what the word "unique" means.
