Love Rossman and his analogies. lol
If you agree with Louis but don't know how to setup something as complicated as pfBlocker-NG, you can try other DNS (DoH/3) based adblocking which IMO is just as effective;

Not sure how to use dnscrypt-proxy to set up DoH/3 resolution? Check out the only software I've ever recommended anyone ever pay for: YogaDNS
Swapping DoH/3 providers is as simple as adding them, and setting a routing rule. Hell, your router may even be DoH/3 compatible and you'll be able to set this network wide.
Test it out.
You're not having issues because it's very likely it's limited by your ISP regardless. There's simply no way a consumer ISP (or VPN) is allowing 1200 simultaneous UDP connections. So you could likely set it to a million and have no issues. Because you're being limited to ~250-500 at the protocol level by your ISP/VPN. lol
Situations like this, torrent priority is even more important because there's a high likelihood you're not able to connect to peers you otherwise would be able to if you were using priorities...
