The probability of a statistic such as the t-test being less than .01 is determined when you have rejected the null hypothesis. This is because rejecting the null hypothesis means that the observed results are unlikely to have occurred by chance alone, and thus the difference between the groups is considered statistically significant with a high degree of confidence (i.e., probability less than .01).
