Question

Why do all aircraft have a tiny hole in them

Answer 1

The outer pane is the primary structural window” simply means that, under normal conditions, the outer pane bears all of the stress of cabin pressurization. The inner pane is redundant, a failsafe “designed to hold the cabin pressure in the event that the outer [pane] is fractured,” which i would say is “an extremely rare event.”
The hole serves as a bleed valve, allowing pressure between the air in the passenger cabin and the air between the outer and middle panes to equilibrate. This tiny little hole ensures that cabin pressure during flight is applied only to the outer pane.
