For example, if your rating is 929, there are 3878 players with ratings higher than yours making you tied for 3879th with everyone else at 929. It you're at 924, you'll have to guess that maybe half of the players in the 920s (4811-3878=933) are higher than you so your ranking is roughly 4344th (3878+466).
