Depends a lot on definition. I suspect I am in the top 1% of all anglers IF you consider a general knowledge of many fish and fishing circumstances.

I have fished for and caught marlin, bonefish, tarpon, gar, trout, steelhead, salmon, bass, catfish, char, sailfish, giant trevally, jacks, three species of tuna, yellowtail, roosterfish, cubera snapper, amberjack etc.,etc. I know a bit about an awful lot of fish and fishing.

I am only an expert on steelhead, and am a fairly knowledgable salmon angler. This all adds up to a giant SO WHAT! The guy who has the most fun wins. End of story.
