It simply means that on the scale of particles the laws of nature that we know and love and have been brought up with simply don't apply.
It has always been the popular notion to imagine the atom as a proton and neutron in the centre with electrons flying around. A bit like a solar system. This is a good way to explain it and one we can understand but in reality they are not like that at all.
In fact, they are dimensionless concepts that don't really exist in a way that we can readily apply to our everyday experience.
The first thing you are told at University when you do your PHD in physics is to forget everything you have been taught about physics because nothing that you have learnt at school or seen on the T.V. comes close to this weird and chaotic world.
