They aren't. Angiosperms are usually considered the most successful land plants.
That is actually not true. The vast majority of animals, including vertebrates and invertebrates, are insects. All insects live on land. As for vertebrates, three of the seven classes are types of fish, and fish species equal the number of terrestrial vertebrate species, at approximately 32,000 types of fish compared with 10,000 reptiles, 10,000 birds, 5,000 mammals, and 7,000 amphibians.
Angiosperm
I haven't counted recently, but I can tell you there are at least 5,000 different species of frogs. They are among the most diverse groups of vertebrates.
