why co co2 carbonates and bcarbonates are not organic?

In late 18th and early 19th Centuries, many chemists believed that a “vital force”, a mysterious and presumed property of living things, was needed for the formation of organic compounds. They believed that in the absence of this “vital force” of living things, no organic compounds could be formed. Therefore, compounds are classified as organic if they have "vital force". Otherwise, compounds are classified as inorganic.

At that time, carbon monoxide, carbon dioxide, carbonates and hydrocarbonates had been found in nature. These compounds seemed no relationship with living things, and seemed to be not related to "vital force". Under such circumstances, these compounds were classified as inorganic.

Although the theory of "vital force" was proved to be incorrect, carbon monoxide, carbon dioxide, carbonates and hydrogencarbonates are still classified as inorganic nowadays.

Originally organic chemicals were defined as coming from living organisms. That has been expanded to include almost all carbon compounds with some exceptions. The exceptions are those you listed. These do not necessarily come from living organisms. CO and CO2 can come from burning. Then reactions with inorganic substances like water and acids lead to the formation of carbonates and bicarbonates, again not from living substances.
