VPN is a secure channel between a device and a remote point. Traffic is encrypted inside the channel, so outsiders only have access to service crumbs: the fact of connection and the total volume. It does not provide complete invisibility, but it significantly reduces the collection of metadata and reduces the risk of leakage.
