They do have a web client, but not WebRTC. See this reverse engineering of their protocol: https://webrtchacks.com/zoom-avoids-using-webrtc/
TBH I don't really understand their rationale. Nothing about it strikes me as "better" than WebRTC.
To allow meeting participants to use the web client to connect to a meeting requires the meeting host to explicitly enable the option in their advanced settings (it is disabled by default).
