How is the reputation with Crypto Gambling Foundation?

I was going through some gambling pages in Bitcointalk and saw that a few sites were certified by Crypto Gambling Foundation. (https://cryptogambling.org/)
Can I trust all the sites verified by this page 100%?
They seem to have most of the main sites such as Bustabit, Primedice, Stake, Bitvest, Bustadice, Cryptogames, Cyberdice, Bitdice and this new site called Rocket.
