You accidentally erased a partition on your Mac storage drive. Further, you continued using the drive and saved a few picture/documents on the erased drive. In this case, macOS may overwrite some of the older files present on the erased partition by the newly saved files.

Data overwriting is a common reason for permanent data loss, which typically happens due to continued read/write operations on a storage drive, even after a certain data was deleted or lost somehow.

However, in absence of Time Machine, the only way is to use a tool that can ascertain the feasibility of successful data recovery and offer an optimal course, accordingly.
