LIGO is designed to detect a change in distance between its mirrors 1/10,000th the width of a proton! This is equivalent to measuring the distance to the nearest star to an accuracy smaller than the width of a human hair!
LIGO’s advanced detectors are already three times more sensitive than Initial LIGO was by the end of its observational lifetime
The bottom line is that the sensitivity is better than it was at the beginning of O1; we expect to get more detections.
