Great! 62% for White is pretty good against opponents around your rating consistently. I wouldn't worry about this statistic much though. Personally, some of my best games have been with the Black pieces - yet my statistic indicates I win slightly more with White (around 55% last time I checked). This is because I know my openings really well from the White side (I love the Queen's Gambit right now, but my go-to opening used to be the Scotch Game and I still sometimes play it for White). Because we score better with one side, that doesn't inherently mean that we are magically better with that faction; just that we score slightly better because we know more opening theory for it.
To improve with Black, I would try investigating into deeper mainlines for White with the mindset of how to counter if you were Black. A lot of my Black pieces repertoire was created through playing that opening as White and having trouble facing x-line from Black so I switched to playing it from the Black side.
Once we escape opening theory, then chess typically shifts into middlegame and endgame motifs where positional and tactical warfare begins: luckily this is colorblind. Learning chess in general, your winrate for White and Black will likely stabilize a bit more.
I'm trying to climb into 1100, currently winning 62% with white (mostly Scotch Game) and 46% with black. As black, what openings should I focus on or what other tips should I take onboard to level my playing ability across both colors?
