The convetional wisdom is the opposite, But here, conventional wisdom

It's certainly possible (in POSIX, anyway) for the stack bounds
to be unlimited (given sufficient real memory and/or backing
store) and the heap size to be bounded.   See 'setrlimit'.

The sizes of both heaps and stacks are bounded, because
pointers have a fixed number of bits.  Certainly these
sizes can be very very large, but they are not unbounded.

The earlier sentence was confusing, as the sentence construction
suggested "unlimited" was a general term rather than one with a
specific meaning in POSIX.  In any case thank you for the
education.
