I'd compare it to the mail. UDP is regular first-class mail. You send a letter, it probably gets to the address on the envelope. But it might get delayed, or even simply lost, and you'll never know.
TCP is like certified mail. It is sent by the same physical systems, but it is tracked and you get an acknowledgement that the recipient received it.
