I think that their theory might go something like this when extended:

Whatever early state of the universe was in there was a huge set of possibilities but a smaller set assemble into anything and even smaller set can assemble into things such as atoms that have stable eletron orbits that can mix with other atoms giving rise to chemistry.

It's not saying this option is inevitable but some option is. We happen to live in the option that gave rise to atomic matter that self interacts allowing to assemble more complex matter.

Of course this doesn't include dark energy and dark matter which presumably doesn't interact chemically with the matter we are familiar with but none the less could still be a component needed/useful for life.
