ALl ports except port 22 are closed but firewalls aren't on need help

So nothing is working. All ports are closed (being filtered) so they aren’t working) why is this?

Here is my nmap scan results

nmap -sV
Starting Nmap 7.92 ( ) at 2022-07-23 07:56 Eastern Daylight Time
Nmap scan report for
Host is up (0.0096s latency).
Not shown: 988 filtered tcp ports (no-response), 11 filtered tcp ports (host-prohibited)
22/tcp open  ssh     OpenSSH 8.2p1 Ubuntu 4ubuntu0.5 (Ubuntu Linux; protocol 2.0)
Service Info: OS: Linux; CPE: cpe:/o:linux:linux_kernel

Service detection performed. Please report any incorrect results at .
Nmap done: 1 IP address (1 host up) scanned in 8.59 seconds;

I’ve checked ufw status and it says disabled. and iptables status it says dead (disabled) why is this?

service iptables status
iptables.service - netfilter persistent configuration
     Loaded: loaded (/lib/systemd/system/iptables.service; enabled; vendor pres>
     Active: inactive (dead)
       Docs: man:netfilter-persistent(8)

ufw status shows ufw dead (can’t copy and paste it in)

netstat -tulpn
