It's always nicer to beat a higher rated player than yourself. In this video I analyse a victory I had last year when my Blitz rating on Lichess.org was 1299, and my opponent's was 1450.
I have since added around 80 points to my rating, whilst my opponent only 3. I know that as my rating gets higher, the progress will be slower, so analysing games is a skill that you need to develop in order to improve.
