I’ve always known that AV1 and Opus are more efficient than HEVC/VP9 and MP3/Vorbis, but exactly how is this achieved? Is it just a matter of more efficient compression?

It’s a combination of that. Compression technology and technology in general are built upon the successes and ideas of the previous generation. What can happen is a bunch of methods are created and the popularity of them dictates their future. Eventually those compression algorithms are put into hardware allowing future devices an easier time using it.
So essentially experimental algorithms are adopted by the industry and power users and whatever ends up winning that popularity contest gets added to weak devices such as netbooks and TVs.
We’re currently at the point where AV1 is starting to be deployed in hardware and streaming services have been switching to it for efficiency.
