No, almost nothing is truly "permanently" deleted with a simple click; deleted data usually remains on a drive until overwritten, but can be securely erased with specialized tools or full disk encryption, while online data persists on servers, backups, and caches, making complete removal challenging but possible through service-specific "permanent delete" options or data destruction methods.
In reality, deleting a file doesn't immediately remove it from your hard drive. Instead, the system just marks that space as available for new data. Until something else takes its place, that file can still be recovered. For anyone unfamiliar with how digital storage works, this concept can be a bit tricky.
