It depends if your overwritten files are on HDD or SSD, and how many times they got overwritten, but there is still a chance you can still recover them unless data was secure deleted with some software or bios.
Few years ago I accidently deleted and written over some files on my HDD and I managed to recover them but not 100%, because some files are harder to recover.
Lesson earned for future, always keep physical backup on paper for important stuff like seed words.
