question about the fool and the devil card im new

tm89

Hey yall
I am new at tarot reading im still studying a bit I received 3 decks for my birthday lol
but I did do a reading for a friend the question was about if a friend of hers was going to go through with a marriage(long story smh lol) I was doing fine until the outcome I got the devil as the basis, the fool as the challenge and the outcome was lovers, I know that the lovers are the same 2 people in the devil card, ive never had the fool devil and lovers show up in a spread at the same time, I know that some say the devil with outcome of lovers could be darkness coming into light but the fool crosses the devil, im confused a bit. the crowning card was the 2 of pentacles and in the past position its the 9 of pentacles Im using the rider waite tarot deck
