isn't 5% a huge edge? is there any casino game where the house has that high an advantage?

There are a bunch, most notably American roulette (with "0" and "00"), sports betting, money-wheel games, some slots and video poker, assorted craps bets, custom table games like Sic Bo, and most egregiously keno, whose house edge is generally in the 20-30% range.
Wizard of Odds is an awesome resource for stuff like this.
Here's a page detailing the house advantage of a bunch of games--and this is all assuming perfect play if skill is involved.
