"We can't win them all. It's just not going to happen," McCarthy said after the 2-2 draw against The Seasiders on Monday night.
"It is two points dropped, being 2-1 up with just a few minutes to go but it's a tough old league and that's been proven again tonight.
"The status quo remains the same between us and the two teams closest to us, but of course Cardiff will have a say, Sheffield United will have a say and a few others.
"The target for promotion is 92 points, but all we can do is make sure we get our own tally of points."
