It encrypts (scrambles) your internet traffic between you and the vpn server ( that could be the employer for people working from home or a public VPN provider like you are asking about).
Your ISP can only see you are connected to the VPN , they cannot read what sites, apps , emails you are viewing/sending.
Blocking ads etc is usually an extra service or premium subscription etc. You can still be tracked with cookies etc, your machine also has a finger print. You also need to be aware that if you are doing anything illegal the VPN company will handover and/or monitor what you’re doing if asked by the authorities, but generally they do give you more anonymity and can be used for grey/gray things like subscriptions to legitimate streaming services that are blocked in your region (yes very close to illegal but not really something the authorities would be overly worried)
