The big CS conferences are around 20% acceptance rate, Science and Nature are around 7%. So while easier than Science, that is still quite an accomplishment!
Getting a paper into high-impact conferences are definitely still an incredible accomplishment, but comparing these acceptance rates is a bit misleading. Those CS conferences have a very narrow scope, while Science and Nature literally cover any topic pertaining to science and nature... including CS :).
