Al Jawaab Billahit-Tawfeeq
Although what you mentioned is correct regarding many school of thoughts nowadays, but the Ahlus Sunnah wal Jama’ah only adhere to four school of thoughts – Hanafi, Syafi’e, Maliki and Hanbali.
There is an extensive discourse regarding this issue and to try to compress everything here will not do justice. It is highly recommended that the book ‘The Legal Status Of Following A Madhab’ by the prominent Mufti Muhammed Taqi Usmani (damat barakaatuhum) be read for more precise understanding regarding madhab.
Apart from that, please visit these links to help give a better understanding regarding madhab too:
