Expected Behaviour:
PiHole should only have 1 IP address and only be accessable from 1 IP
Actual Behaviour:
PiHole has 2 IP's 192.168.1.3 and 192.168.1.165
Debug Token:

Have you rebooted since you installed the Pi-hole software? And how do you have the Pi set up to be addresses? Check /etc/dhcpcd.conf and see if there are two IP addresses configured. Also check /etc/network/interfaces to make sure it is the stock Raspbian and has not been changed to add a static IP address or DHCP sourced addressing.

I edited dhcpcd.conf cause if has some other addresses in it but not the .165 address but this is the output of sudo nano /etc/network/interfaces

iface eth0 inet manual will set that interface to only use /etc/dhcpcd.conf for it's static IP and not request an IP from the DHCP server.
Should I use iface wlan0 inet manual since in using WiFi instead of ethernet
Yes, but first run ip addr to list the IPs assigned to each interface to make sure eth0 doesn't have anything. If there's no cable to it, there shouldn't be, but it's good to check first.
Ok then should I delete that wlan1 entry?
I can't say for sure, I don't know how you have your network set up and what interfaces are needed.
It's just a retropie image with PiHole running in the background over WiFi... I have DHCP disabled in my router and DHCP enabled on the PiHole
Can you post the output from ip addr and we can see if there's anything on that interface?
Here you go. Also seeing a few ipv6 addresses that aren't needed anymore possibly.

Yes, change the wlan0 line to manual and remove the wlan1 since that's not an active interface. The IPv6 may or may not be removed with manual but be aware that if your network is IPv6 and you are not blocking with IPv6 in Pi-hole you will probably have some ads leak through.
Yes I am blocking over ipv6 so I don't want to delete all the adressess just the one currently in use. Am I right in assuming that?
Actually where are the ipv6 addresses saved?
They are all dynamic so they are dynamically generated via a process called autoconfiguration or SLAAC. I'd suggest a read through Use IPv6 ULA addresses for Pi-hole for some more on IPv6 and Pi-hole.
I've actually read that and in my particular router ula is not supported at least not without running custom firmware
Okay, the dynamic addresses can change, so that's something to keep in mind with Pi-hole and if you see ads coming through. They can not be removed through a configuration file change, only disabled completely.
Ads aren't really leaking through from what I can see but just trying to clean things up
