Read it carefully, they are irrelevant only in classical physics. Give that to any quantum physicist and their respond would be "I told ya so". For macroscopic practical daily life scenarios, it doesn't matter because how can naked eyes deal with such a thing?

But when you are dealing with extremely small scale problems such as with atoms or when you dealing with great velocities, the universe behaves and was found to be much different than it first appeared. And quantum physics mostly deals with high speeds or atomic scales. Think of quantum mechanics as the "polished" version of classical physics, it tells the whole story of physics and not just an estimate.
