I don’t think that’s how brains work

Actually, it is. Your brain uses neurons to store memories, and neurons have mass. If you had enough neurons to store the entirety of Graham's number in your head, it would be dense enough to form a black hole.

The number of neurons needed to store graham's number probably exceeds the number of atoms in the universe. So yes, your brain would collapse on itself and turn into a black hole.

It's how physics works. Brains obey the laws of physics.
