Come to talk of bitcoin peer to peer transaction, I believe a peer to peer transaction definitely would require two parties meeting to do transfer one on one which do not also guarantee ones safety of the account holder
You don't need to meet at all and the bitcoin being traded can be placed in escrow prior to the trade for safety. There are plenty of platforms such as Bisq and Robosats which have such a system in operation.
Although CEX are not pseudo or anonymous and they demand for kyc before depositing with them but the peer to peer with the CEX are anonymous and ok to go with just as the DEX is.
Not correct. Trading peer to peer on a CEX is not in the least bit private or secure, since the CEX watches everything you do, reports it all to blockchain analysis companies, and has complete control over your bitcoin while the trade is taking place. You cannot trade peer to peer on a CEX - it is always peer to CEX to peer, with the CEX being a centralized third party. All CEXs which offer "peer to peer" are simply using the term as a marketing gimmick - it isn't actually peer to peer at all.
