"White's score" = wins + half of draws. "±" is an approximate 95% margin based only on the number of games. It does not cover sampling bias or related games (the same players appear many times), so real uncertainty is larger. "How common" = share of all sampled games at that level that reached this position. Ratings are Lichess ratings; they are not interchangeable with Chess.com or FIDE ratings.
