This discussion helped be understand the distinction much better, hope it helps!

Degeneracy is the number of ways of achieving a given energy state, while entropy is the probability that the system will be in a particular state.

Degeneracy and entropy are also directly related, which means that the higher the entropy, the higher the degeneracy.

Degeneracy is the amount of states a particles can exist in. Entropy is a measure of disorder in a system. While they both may seem similar, degeneracy is describing the actual number of states and entropy is measured in J/K

Entropy is the probability that the system will be in 1 particular state, while degeneracy is the number of ways you can achieve that energy state.
