Hello can anyone explain how to do caesars cipher cryptoanalysis technique?

However I am mostly confused with how you got the number J(14) W(33) L(17)

I know the most frequent letters are N(4) P(3) W(3)

I dont understand this:

For most likely:(19) N(4) =J(14)

For second likely:(23) P(3) =W(33)

For third likely: (33)w(3) =L(17)
