Answer 1

There are gaps and holes, you just need the air to escape slow enough that your life support systems don’t have to work that hard to maintain pressure.

There are multiple layers, seams, sealant and materials that essentially make air escaping like trying to run through a very complicated maze to the point where the total leakage is effectively negligible.
