It is kind of hard to interpret something sight unseen. Try posting the results you are getting.

GMM Esti | Test0 | Wald | 42.57 | <.0001 | a=b |

this is the result.

Can I conclude that a is different from b?

There is strong evidence that a is not equal to b based on what you have posted. AKA "A and B are different"

Now, I see that you are estimating these parameters with GMM so this might be some sort of complicated system. For that reason I cannot make any comment on the usefulness or appropriateness of this test statistic as I don't have much context.

Good luck-Ken
