Anyone only has access to your public key if you give them access to your public key. So no, not really. They should have access to it. It’s not something you should keep private, but SSH shared keys aren’t PGP shared keys. There’s no key servers for SSH shared keys.
Then, anyone in the world can verify your signed statement using your public key.
Of course. The only barrier is the possession of your public key. I really don’t understand what you’re getting at here. Anyone with your public key can verify a PSK signed statement you made, which obviously is predicated on them having access to the key.
