And the probability is 90% of people who voted for Revan have no clue who Thrawn (or any Star Wars character, other than those in the movies, or the two KOTOR video games) is.
As I said earlier, go to a Jar Jar Binks fansite (there must be one out there) and do a poll about who is more powerful, Jar Jar or Darth Vader, and you'll see Jar Jar win the poll.
The fact that Revan's not winning by a landslide speaks volumes about how good Thrawn really is, to give Revan competition on what basically boils down to Revan's own fansite.
