Pi bonds are bonds formed by side by side overlap of two p orbitals. Sigma bonds are two electrons in a cylindrically symmetrical cloud between two atoms. Pi bonds occur in p orbitals and sigma bonds occur in s orbitals.

pi bonds are also only found in double and triple bonds while sigma bonds are found in single, double, and triple bonds

Sigma bonds are end to end interactions that allow the atom to rotate around the internuclear axis and pi bonds are overlapping side by side bonds that don't allow atoms to rotate. There can only be one sigma bond between two atoms while there can be more than one pi bond.

Why are sigma and pi bonds relevant?

They are used to predict the behavior of molecules in molecular orbital theory.

Sigma and pi bonds are also relevant as part of the valence bond theory, which takes into account the wave nature orbitals. It is also significant because it helps understand the concept of hybridization.

Are d-orbitals ever relevant in these situations?

Once you get to o-chem, sigma and pi binds really help one predict how molecules interact and how they work together in organic processes.
