That's right.
In Distinct arrangement: A circular arrangement of different people: For distinct objects the total number of permutations = (n - 1) !

Non-Distinct Arrangement: When the objects in the arrangement cannot be identified separately then the arrangement is non-distinct.
For non-distinct objects, both clockwise and anti-clockwise arrangement would be the same. Therefore, the total number of permutation = (n-1)!/2
