A VPN provides an encrypted tunnel for your traffic, so your ISP can only see that you are communicating with the VPN server. However, the VPN provider can see the hostname/IP of the servers in order to forward the traffic to its destination.
Ideally the VPN provider does not monitor or keep logs of the connections, but this is not always the case. A VPN offers privacy from the ISP or from other clients connected to the local network when using public WiFi.
It can also provide some level of anonymity, because the server that you are connecting to will only be able to see the VPN IP address connecting to them, instead of your home IP address. It is possible to still be identified by other means besides your IP address, like using cookies or browser fingerpinting.
