 The account balance on Etherscan comprises regular transactions and internal transactions. Internal transactions, despite the name, are not _actual_ transactions that change the state of the chain. They are value transfers initiated by executing a contract ([source](https://ethereum.stackexchange.com/questions/3417/how-to-get-contract-internal-transactions)). Since internal transactions have no signature, they are **not** included on the blockchain and cannot be queried with Dune Analytics.
