How to interpret "marginals" in case of the zero-weighted binomial model?

It may be noted that in the case of ordered probit, one gets a set of numbers as marginals as there is multiple ordered category of the dependent variable. Binomial also may have values between 0 and N. Is the default marginal computed by STATA for binomial regression (say with atmeans) is true for the average or expected value of the dependent variable as well as all independent variables. For example, if Y is our dependent variable, and X is an independent variable and the marginal of X is given as 0.12, can I conclude that one unit increase of X at its mean will lead to 0.12 units of increase in E(Y)?
