they can be interchangeable. those two numbers refer to their diameter. there should be other numbers specifying a width

27" and 700c are "close enough" for tubes, but not for tires.

700C, sometimes AKA 28” has a 622 mm bead seat diameter.
27”, not to be confused with 27.5” has a BSD of 630 mm.
If the width is OK, the tubes are interchangeable.
There’s another 28-something” with a 635 mm BSD.
Those are usually wider, so not compatible with the majority of road bike sized tires. But might interchange with 29er and hybrid tires.
