The odds are always crazy and get more "accurate" once all songs are known. I wouldn't pay too much attention to them. The UK is doing good in the odds because they're sending a big name and Turkey/Azerbaijan/Greece are up there because of their recent good results. But that is all going to change very soon.
Betting Odds are pointless at the moment, bookies are just decreasing the odds of those countries which "historically" do well & any hype about any entry gets the odds slashed. Until April when the Odds settle we won't be knowing much
These lists don't really tell you anything about the possibility of winning or qualifying because it's based on results from the previous years and doesn't take into account the songs from this year. Then I can understand why Germany is at the top, since they won last year.
