The hand possibilities are the same. But for on a server, people can play at multiple tables at the same time...giving them more patience to wait for their good hand. It also seems (at least to me) that the 2% chance hands seem to hit a lot more on servers than in live...and you'll get a lot more pre-flop all-in calls on the server as well. I think its because its easy to join another table if you get knocked out on another.
