Doesn't help to make clear if you report the t-value or the p-value of a t-test. If it's the t-value, you would at least need to report the related p-value to judge if the mean difference is statistically significant or not. If it is the p-value depending on the chosen alpha level (commonly .05) and depending on if it's one or two-sided, it's likely not statistically different because the value is too high. And if it's the p-value, you would also not interpret this directly as a probability of there being a difference in the means (at least in a Frequentist framework).
