Those are definitely individual stars. They might between us and the Triangulum galaxy.

Well the stated resolution of Hubble is about 3 orders of magnitude smaller than necessary to resolve VY per my likely flawed calculation, so we're roughly within an order of magnitude of each other.
Either that or all those stars are uuuuuge

It doesn't matter if the star is smaller than the pixel. You can see them individually as long as you can resolve the distance between them.
Under the simplifying assumptions that the image is square and encompasses the exact galaxy width, that's about 22 trillion km (or ~11,000 VY Canis Majoris) per pixel. So I guess we're not seeing individual stars (edit: in the target galaxy) - or my math is also off somewhere.
