TIL UDP Traffic runs on TCP.

"TCP/IP" is conventionally used to indicate the whole protocol suite; including UDP, ICMP and sometimes even ARP.

Technically the parent protocol is IP.

In all my years I have never heard someone suggest that TCP is a catch all term.

I've seen many references to TCP/IP as meaning IP + everything-on-top, usually when talking about other networking technologies like UUnet, OSI, etc. Also as the TCP/IP stack, usually meaning the (Free)BSD networking code used in other systems.

It's not that TCP is a catch-all term, but "TCP/IP" is often used that way.

https://en.wikipedia.org/wiki/Internet_protocol_suite

The Internet protocol suite, commonly known as TCP/IP, is a framework for organizing the set of communication protocols used in the Internet and similar computer networks according to functional criteria. The foundational protocols in the suite are the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), and the Internet Protocol (IP).

For that matter, the classic networking text by Douglas Comer is Internetworking with TCP/IP and it does cover UDP, ICMP, ARP, DHCP, DNS, etc.
