Interpreting the results based on Granger Causality test
(0.0053726552728412666, 0.9415686658133314, 1), that 0.005 represents the test statistic Yes,
0.94 represents the P-value - Yes.
and 1 the degrees of freedom? No.
And 1,2,3 and 4 are ordinary serial numbers and not, degree of freedom.
At 10% level of confidence, you need at least 2.71(value of Chi-square). You have computed the chi-square = 2.576 and therefore, the null-hypothesis is acceptable. Your assertion  - the null hypothesis can absolutely not be rejected- is valid in this particular case.
