Maybe this could sound like a dumb question, but this has been troubling me for a few days.
Let's suppose that I buy a domain in porkbun, example.com
And I want to manage it using an existing Hosted Zone on AWS Route 53 called unrelated-host.org.
As far as I know, in order to achieve this, one just have to change example.org NS entries to point over the NS entries of unrelated-host.org.
However, when I try to access example.com I'm getting no response and that's why now I'm not sure about this.
Hope somebody could give some clarification about this, regards!

The domain names absolutely have to match. You can't configure Route53 to be the authoritative DNS server for the domain unrelated-host.org and then just expect that to magically work for the domain example.com.

No, that's not how DNS works at all. There are many customers using those same domain name servers. The domain has to match in order for those name servers to know what domain in Route53 the DNS requests are for.
