P-value is really high???

Hi, I have run some data of paired t-test (before and after the treatment), but the p-value is high p=3.7. What does the test suggests? Is there no difference? Thanks!

A p-value less than 0.05 (typically ≤ 0.05) is statistically significant. ... A p-value higher than 0.05 (> 0.05) is not statistically significant and indicates weak evidence against the null hypothesis. This means we fail to reject the null hypothesis and cannot accept the alternative hypothesis

The p-value must be less than 1. When it is less than .05, it means a significant difference. Only t-value can have the value of 3.7. Usually, when the t-value is 3.7, it already indicates a significant difference.

Hi, I realized that it seems the concept “outcome” is different from the term “output”. Taking the grandparent training project as an example, what is the “outcome’ referable?
