Hawking did indeed write that in the 1988 book, A Brief History Of
Time, but that isn't what he wrote in his science papers. He was
trying to simplify / interpret, in a book intended for the general

A detailed explanation is here -

In reality, what’s happening is that the curved space around the black
hole is constantly emitting radiation due to the curvature gradient
around it, and that the energy is coming from the black hole itself,
causing its event horizon to slowly shrink over time.

(But the split quantum pairs description is still easier to understand)!
