Sort of. It has to do with certain matter (they have to be neutral bosons i.e particles with integer spin and no overall charge) being so cold that there arent really any higher energy quantum states for things to be in. So everything is essentially in the same state and functionally indistinguishable. Which is why not everything can form a bose einstein condesate.
It is a combination, if the particles’ positions don’t overlap then you don’t have a condensate, but at low enough energy and close proximity these particles will overlap
