It's correct but defenders also choose where that happens. 100% of the time on the locations and conditions that the defenders choose / allow. As a defender i need to be right 100% of the time, sure, but i can make it so that the things i have to be right about are very well known to me, unknown to others, maybe even extremely unlikely to be to known by others, difficult to get to know, (...).

How do I hide the underlying technology of customer-facing systems? How do I hide which SaaS services I use?
