Why Is My Outgoing Transaction Still Showing 0 Confirmation?

Please note that all outgoing transactions are first sent to a mempool waiting to be processed by miners. Then, miners may choose to process the most efficient transactions based on the transaction fee or the transaction time.

This is because most of the blockchain explorers will only provide transaction information that is confirmed by at least one node. Please refer to the following diagram:
