Null or dead addresses have no private keys to them which means that no one has access to them.

That's correct because without private keys we cannot sign the transactions of transferring out of tokens

An example of this is the BEP-95 gas fee burn on the BNB Smart Chain

BEP 95 is a continuous process as it burns the required amount of tokens at each block creation unlike the burn function emcarried out at intervals .

You have explained everything in great detail . Good luck
