What you're asking about is part of the basics and beginnings of the Bitcoin field. This question suggests that your experience in this field may be limited. I advise you to gain the necessary expertise and knowledge because, with this minimal experience, you could become an easy target for scammers.

Don't worry; no one can withdraw money from your Bitcoin wallet; you provide this public address for him to send money to you. However, please do not make the mistake of giving them your private key or recovery phrases. I recommend avoiding any transactions or involvement in deals until you familiarize yourself with the basics, such as types of wallets, common scams, and protective measures.
