While it is true that the standard normal distribution has a mean of zero and a standard deviation of 1, t-distributions have slightly different properties. Specifically, the mean of a t-distribution is also zero, but its standard deviation depends on the degrees of freedom (df). For larger df, the standard deviation approaches 1, but for smaller df it can be larger.
