Star Absorption increases the chance of your Servant getting most/all of the critical stars generated, thus increasing his/her chance to deal critical hits.

The percentage are so high because, I guess, there are always 5 cards to take in account, from 3 characters, with different degrees of natural absorption capability. There's also an hidden algorithm to define who will get more stars regardless of said capability. Even with 1000+%, a Berserker with only 1 card on the deck might not get more than 20% chance with 30 stars on stand-by (unverified ratio here)

The more the better.
