I see, so both methods are different in general. But why do these methods even agree to first order and why is ##\frac{d-2}{2}+\gamma## from the Callan-Symanzik equation agree with the anomalous dimension from Wilson's RG?

I have taken a Quantum Field Theory course recently in which we first derived the Callan-Symanzik equation and then discussed Wilson's Renormalization. However, I don't think I have a clear understanding of the procedures and how they relate to each other. For the sake of this question, let's...
