How they "know": The copyright holders join a torrent swarm and log all IPs that give them pieces of their copyrighted content. They then send infringement complaints to the IPs' ISPs alleging that someone with that IP was infringing on their copyright at the given date and time. There are a number of reasons an ISP might not know who had a given IP at a given date and time. DHCP and CGNAT are two big ones. And the rare individuals who choose to fight do sometimes use that as a defense. However, those technologies have a purpose other than anonymizing activity. A residential ISP who took active measures to obscure their customers activity would have a harder time defending against a complaint of negligence.

DHCP can be set up to make things harder, but most people's IPs don't change very often. ISPs don't want to make it impossible to tell who had an IP address at a given date/time because they need that information to fight other forms of internet abuse (spammers, phishers, hackers, malware, child porn, etc) as well as other legal requests they see from police and certain three letter agencies who file the proper paperwork with the ISPs legal department. This is generally a good thing and makes the internet a safer/better place. Any ISPs who made it impossible for themselves to tell which customer had an IP address is going to act as a safe haven for bad actors and they'll get blacklisted from many other networks pretty quickly. Only the largest ISPs can ignore abuse issues on their network without fear of being blacklisted and their IP space null routed.

You're by no means incorrect but the strategy you're speaking of here to determine where warez is going is .. about 25+ years behind and even then network engineers used it as kind of a "look, they're not netengs, they're not going to understand how we encap/decap packets and uniquely identify their chain of custody, so just say something simple so they get the idea." It also fell flat on its head when it hit the "is an IP a person?" argument. Every file crossing the line is fingerprinted and various ISPs give various copyright-track software vendors or licensors direct access to track those pre-determined fingerprints and report problem to ISP for customer to mitigate or help prepare for subpoena. There's a lot of other ways this stuff is tracked I won't get into and the environments even more direct now with all of the ML tools. Webhosts and social media apps do the same thing so they can have smaller abuse departments digging for CSAM content. Data exfiltration is a huge space. As soon as a new lady gaga video is uploaded to Vevo, the fingerprint was already determined, and the copyright bots have alread been scanning the internet for that file for days/weeks. Watch a new music video release on youtube, you'll see attempts to copy it get hammered immediately. DPI and MITM-TLS which a lot of people blindlyaccept by accepting various free ISP features basically takes most of the end users privacy away in the end anyway. They're all reselling your data, ISPs and most VPNs are scum. These are scenarious that someone with experience at a major CDN would be very familiar with. We do the same thing tracking every unique object on the entire platform.
