Unfortunately, you are confusing several issues. Imagine two different trains. One will make a 'best effort' to get to the station at the highest speed but will not guarantee that the data will get there. Let's label that train "UDP." It has a source address, a destination address, and some information about the size and type of data. The other train though, called "TCP", is slower but carries more information other than the source, destination and amount of data. Before it leaves the station it will make a 3-way handshake with the other station to guarantee that all of your data will be transferred. If there are any problems, the data will be resent. With UDP, the fast train, no connection nor any checking will be done. It will only keep pushing data until the job is done.
