Can someone restore my information from the phone I did factory reset and sold ?
If I reset my phone and then sell it, is it possible that someone can restore my information ? Without having access to my apple id or backups ?

Not if you erased it, no.
Ideally you did all in this document:
What to do before selling or giving away your iPhone, iPad, or iPod touch [or if you received one that had not been erased] - "Use these steps to remove your personal information from a device, even if you don't have it anymore." --> https://support.apple.com/HT201351
