If that folder was on the boot SSD and more than a few minutes have gone by, your data are GONE.
There is no residual on an SSD drive that uses TRIM, as all Apple boot SSD drives do. After a few minutes the blocks are pre-erased for re-use and the block numbers are randomized.. GONE.
If that data was on a Rotating Magnetic drive, the directory entry is gone, but the actual data blocks are not erased, they are simply added to the FreeList for re-use. Any additional activity on that drive allocates blocks that may have contained your data, and that activity may destroy part or all of that data.
