Not entirely. The lease default is usually about 24 hours, that computer would need to be completely offline for a day and the IP address would usually need to be reassigned before the device gets a new IP. Even then, the router would probably try to give it the same.
When I moved I unplugged the Jellyfin server about 4 days before the router and it came back with the same IP. I dunno, maybe I have a good router. 🤷♂️
Other things come into play. If you don’t have leases expire often or dozens of devices coming and going repeatedly like a public wifi may have, it’s also stored in ARP tables, saves it some work later when it recognizes a device.

Ah ok. I’d call 24 hours a while ;)
