Labour's still behind but they're well within a relatively normal polling error of making Corbyn the next prime minister. Which is amazing considering where they were at the start of the campaign. They are like 5 points behind right now? And the polls were a full 7 points off last time around. Crazier things have happened.
With the 20 point lead May had at the beginning of the campaign, there was basically no way in hell you could expect Labour to win. 20 point polling errors basically don't happen (which is what I was trying to tell all you Le Pen tards). Now, you definitely should not get cocky and count them out.
