Some say they are the same. It is written on the wiki that, in principle, it can be the same, but in particular cases it is different. What is the truth? What's the difference?

packet - IP, datagram - UDP, segment - TCP

it's probably easier to say this: datagrams - a stream without establishing a connection (example - radio, TV, GPS), packets - ordered packed data for assembling messages with integrity checking on the client side.
