I started playing chess about a month ago and have rapidly rose from 890 to 1270 rating; however, I am winning a higher percentage of games when I have the dark pieces. Having the first move should be better right? I play only the LONDON system as white and I play the SCANDINAVIAN defense against e4.
Well looking at your stats the difference is not too great. It's an advantage to move first but not a huge one. It might mean something tangible in high level play but us amateurs make so many blunders throughout the game that it doesn't make such a big difference.
