Is it possible for one to recover data once a computer has been destroyed?

It depends on what you mean by “destroyed,” but here’s the general idea:

Physically damaged but not shredded: If the hard drive or SSD is intact, professional data recovery labs can often retrieve data by repairing or connecting the drive to specialized equipment.

Severely damaged drives (burned, smashed, or shredded): Recovery becomes extremely difficult or impossible. SSDs are particularly sensitive—once destroyed, data is usually unrecoverable.

Cloud or backups: If the computer synced files to cloud storage or backups, those copies can be restored regardless of the hardware.
