I'm not a layperson (not really, at least) and I strongly feel like the sigma algebra framework is basically a waste of time. Mathematicians love abstracting and formalizing things but it's not useful, paradoxically, if you're trying to actually just do math.

Sigma algebras are primarily useful for modeling less well-behaved probability spaces when you aren't dealing with (a product space of) probability spaces of that can be described by a pdf or pmf
