It has something to do with moderation no? That it is unfair to allow people to take other people's wealth and how it's also not right to get richer without working for it. Also something about it being satan's plan to create strife between people through gambling, which then leads to less focus on Allah and praying and stuff like that.
edit: And of course when you look back at the historical perspective it makes sense because prohibiting gambling prevented the influence from other cultures where gambling was very popular.
