... improvements around 25% compared to AV1
AV2 decoding is roughly five times more complex than AV1 decoding
I'm not sure what these two lines mean or if we can compare them, any help?

I understood it as compression is 25% better : a quality of 10mbps in av1 can be achieved with 8mbps in Av2. But, it needs 5 times more compute power for this 25% gain.

AV2 saves 25% bandwidth at the cost of 5x more decoding complexity.
What does "complexity" mean here? Computation required?
dav1d is the av1 decoder and it’s an insane feat of engineering. Written in assembly, it even eschews the normal c calling convention to get even better performance.
Yes, much higher computation required to encode it, and decode it, both.

Yes
Smaller files but harder to decode
