ELI5: How can we eat raw fish but raw chicken makes us sick?

Does it have to do with living in water / not living in water?

Lets be clear here. If you take one chicken, and one fish, and kill them both at the same time, you are just as likely to contract a disease from one as the other.

However, chicken processing is gross. Same with pork and beef. Fish is kept cleaner for the intent of being sushi, and is even more expensive if it is sashimi grade. You can do the same for any meat. Steak ~~Tar Tar~~ tartare is raw beef, and it is delicious. Raw pork and chicken are slimy and kind of gross, but if it was kept to the same standards would be perfectly safe to eat. 

*edit. It's Steak Tartare. I've never seen it spelled, hopefully is better now.
