It is indeed and your hard-won Pi can do even more. Here's a couple of future tweaks you can try.
Install your own DNS server using a package called Unbound. Instead of using an external DNS server like Google you'll be using your own DNS server right there alongside Pi-hole. This gives you more privacy because you're not sending your lookups to a third-party. It's really easy to set up and there's an official guide to guide you through it. Just go through it methodically step by step.
Install your own VPN using a package called WireGuard. That will let you send your DNS traffic through your Pi-hole securely even when you're away from home on 4G or another wifi, so you get filtering everywhere. There's an official guide for this one too.
