Most of the islands that were regarded as WB's territory were overrun by pirates after WB died.
Being yonko doesn't have that much to do with individual strength otherwise Mihawk would be one.
You only get called a yonko if you are among the most influential pirates in the world and that is mainly based on territories.
Had Marco cared about that and retaken those territories he might've been called one of the yonko but when the BB pirates defeated them and also probably took over huge parts of their territories and other islands within the new world BB was regarded as the new yonko instead.
