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.

A prime number (or a prime) is a natural number that has exactly two distinct natural number divisors: 1 and itself. The smallest twenty-five prime numbers (all the prime numbers under 100) are:.
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
Note: 1 is not a prime number.
