Note that most people do not learn the full IPA table but only phonetic concepts and sounds that apply to the language they're learning (i. e. what you see in the Phonology section of a Wikipedia article on a language). The full IPA contains a lot of sounds and ways of pronouncing things that you won't need for the vast majority of commonly-studied languages, so unless you are interested in learning how to produce awesome wacky sounds, you only need a much-reduced version for your language study.
