How to interpret the Z Value in probit regression summary


I am running a Probit model in R and find trouble interpreting the Z Value of -9.974. Obviously, it is not the same as the Z-score. So how do I interpret it and is t the same as the t-statistic on my alpha coeficient?

Coefficients: Estimate Std. Error z value Pr(>|z|) (Intercept) -0.5502296 0.0805535 -6.831 8.46e-12 *** X -0.0067435 0.0006761 -9.974 < 2e-16 ***



The z value is the ratio of the Estimate to the Std. Error

-0.0067435/0.0006761 = -9.974

It shows that the coefficient is very far from zero relative to the standard error.
