In this talk I will introduce the statistics of primordial black holes within the realm of gaussian curvature perturbations. I will focus on the PBHs mass function and associated secondary gravitational waves. In passing, I will show that not necessarily an observation of large spectrum of secondary waves in LISA would imply a non-negligible abundance of PBHs.
