There is a difference between abbey beer and Trappist (monastery) beers, Trappist beers are still brewed in monasteries by actual religious orders, in small amount, whereas abbey beers can be mass produced by anyone, and any beer can get the name of an abbey beer.
Belgium probably has hundreds of old abbey beers as well.
To become an official monastery beer (brewed by monks) you need to meet certain criteria, something only 7 monasteries in the world meet. This is an official beer 'badge' like you'd give to wines like chardonnay or for being an official champagne.
As to the link of 'best beer in the world', my site was american, and thus less bias concerning European beers (I'm sure a lot more German immigrants went to the US in comparison with Belgians), whereas yours is obviously a German 'census', and it doesn't look like they were chosen by a select, or large, group who take an interest in beer, but rather a magazine or website promoting the 'luxury (german) lifestyle'.
But tbh, the Belgian vs German beer argument is probably the most common beer argument around (the only worthy one, since no other country can actually compete). I stick to my opinion, you to yours. I have no problem with that.
But might I add, that whenever I go to Germany, the beer is sooooo easy to drink (like water/ not bitter ^^)
