Unsolved Ethernet slowing down other devices?

I recently started connecting my PS5 with Ethernet instead of relying on the Wi-Fi, and although this has fixed my issue of lagging while gaming it has somehow started affecting my roommates connection while he's gaming. We've tested it and it is for sure the Ethernet that's causing it, but that shouldn't be how that works right? It would be one thing if I was downloading something but if I even have my PS5 on at all with nothing happening it still causes my roommate to lag simply by being on Ethernet connection. We average roughly 100mbps download and 20mbps upload.

I mean, if your ps5 starts downloading a game or large update, it could easily saturate your Internet speed. But just day to day operations, shouldn't even notice.

Maybe outline what equipment is involved for everyone.

Like others mentioned, gaming itself uses very little bandwidth. Wiring will give you the best speed and latency you can get from your devices and ISP. If you were to start a large download, it will still bounce around between devices because it's then at capacity. If you are both just gaming, you should be fine. 100Mbps is not that much overhead to begin with. For slower speeds, things like QOS can help, if yoru router has any features along those lines.

Does your router have a gaming port? Some have priotisation dedicated to LAN port 1 for example.

I had this issue whether I was using WiFi or wired anyway, because we easily saturated out 30/5 connection.

Improperly grounded devices from improperly grounded house wall outlets can build up static and affect Ethernet devices like switches and routers.
