No, a deleted Telegram account cannot be recovered. The process is permanent and irreversible, despite it being deleted manually by you or automatically by Telegram.
If you wish to rejoin Telegram, you will have to create a brand new account using your same telephone number. If you have deleted your Telegram account multiple times in a row, you will have to wait for seven to 21 days before you’re allowed to register again.
Note: There are many third-party tools that claim to be able to recover your deleted Telegram account for a fee. Ignore them: these are likely spam accounts. Also, be careful not to download any apps that claim to be able to recover deleted Telegram accounts as they may contain malware.
