Why it missed

Header row was counted as dataThe Galaxy line count included the tabular header and returned 19,160. The number of removed methylation measurements is 19,159 data rows.

Why it missed

Retained and removed rows were reversedGalaxy found 19,698 total rows and 19,159 rows in the inclusive 10-90% range. The agent subtracted those values and reported the complementary 539 retained extreme rows, but the question asks for the 19,159 removed rows.
