No. Both UDP and TCP can be intercepted the same. The difference is that UDP sends a packet to an address. But doesn't have any in built system to check that it arrived, that it arrived intact or to resend if it didn't. There's also no built in way to protect against spoofing or out of order packet delivery. But generally implementations will handle the ones that are important of those themselves.

TCP establishes a circuit, packets are sent, verified and resent if required until the original data, in the correct order is delivered to the application. Also there is some protection against spoofing with sequence numbering. The downside is that time sensitive data might be delayed because of the retransmission and re-assembling. Which is why time sensitive streams like VoIP are usually sent over UDP.

Btw, on my device you sent the message -110min ago, not 110, -110

Yeah, this is a known interoperability thing between kbin and lemmy. So, I'm afraid I can't give you this week's lottery numbers ahead of time.
