1.1. 1.1 is a recursive DNS resolver. So it could really possibly able to access out sites which had been blocked in your country.
It's not because it's a recursive DNS resolver IMHO, but because it's a secured DNS resolver using a secured protocol (DNS-over-HTTPS) that prevents ISPs to see the DNS requests and to block or to deflect them.
Usually when a country prohibits a website(exchange, gambling platform) the website does the same on its side to avoid any legal issue. Hence it doesn't replace a good old VPN.
