Yes, 97 is a prime number.

Because as per prime num definition i.e prime number is a number that is divisible by 1 and itself. 33 is not a prime num because it is divisible by 3, 81 is also not a prime num because it is divisible by 9, 93 is also not a prime num because it is divisible by 3 but whereas 97 is not divisible by any other num expect 1 and itself so, 97 is a prime number.
