mmm Long Answer without getting too complicated

Think of TCP and UDP as doing more or less the same thing, the difference is the

Tcp is connection orientated : your computer sends 5 messages to another computer and the computer that receives the message sends your computer a message "ok i got those 5 messages, you can send me the next messages. If it does not get them it asks the sending computer to resend the messages it did not get.

UDP is connectioneles : your computer just sends all its messages and does not care if the computer at the other side receives them.

This does not means that they do not do any erroe checking is is just done on another level in something called (IT term coming up) the OSI MODEL.

DNS primarily uses the User Datagram Protocol (UDP) on port number 53 to serve requests. DNS queries consist of a single UDP request from the client followed by a single UDP reply from the server. When the length of the answer exceeds 512 bytes and both client and server support EDNS, larger UDP packets are used.
