An issue with taking their claim at face value is they have no incentive to say they can:

- they can keep asking for backdoors to "stop terrorists"

- they're not on the hook if for whatever reason they can't access a particular phone in a very mediatized case

- most targets (the not so sophisticated ones at least) keep using a device the agencies have proper access to

Regardless of their actual technical means, I don't expect we ever get a "we sure can!" kind of public boasting any time soon.
