so every node that uses the default size of 300MB will drop the transactions that have fees of less than 23.2sat/vb but nodes use custom mempool size so the transaction will likely stay longer because it stays in some nodes.
But not all transactions that exceed the mempool size will be dropped, your transactions could be re-broadcast by your wallet or other nodes.

That is why I said nodes uses custom mempool size will have OP's transaction. Rebroadcasting is another issue and some shitty custodial wallets and exchanges doing it to keep the transaction in the mempool even when they used  5/10sat/vbyte for the transaction with hundreds of inputs.
