UDP is just a protocol. I’ve served millions - even billions - of people with UDP media delivery. I use it all the time for all my work communication (WireGuard)
I wouldn’t use it to ping my gateway though, or to join a multicast group, nor would I use it to establish my bgp session, I use icmp, igmp and tcp for that.
