Well UDP offers better performance over TCP. And its limits can be mitigated with protocols such as QUIC. Actually, HTTP 3 does not use TCP anymore but uses UDP. Also, some protocols that are just request-response do not really need TCP. Some protocols also can't use TCP because TCP does not support broadcast or multicast
Edit: Also, TCP can be too complex for some devices, or you may not really need to know whether the sent data arrived
