'Hack your PC' is a pretty vague and general term.

The vast majority of home networks are behind a singular WAN IP address due to Port Address Translation. Any inbound connection that doesn't have a translation for an internal LAN host ends at the router. Port forwarding overcomes this by saying 'any inbound connection on port x, send to internal LAN host'.

Therefore, you still have a singular WAN IP, yet communications on this port don't end at the router but are forwarded to your internal LAN client.

Hence why you rarely want to use the "DMZ" feature (though not a true dmz) on your home router. By virtue of being a NAT device, it does provide a firewall of sorts against outside intruders. Unless, you forward ports to a computer.

Even if it is dynamically assigned address from the ISP, trust me, they have more than enough ways to track what you do.

port forwarding usually uses the internal ip address of your computer. If you have it set to DHCP, then you have to change the router settings to make that DHCP ip address permanent. I have done it to my router and port forwarding works great IIRC some routers have the name Static IP or DHCP Reservation for it
