How important is the microphone used when recording?

Been trying to record vocals on a YOTTO YDM-20 USB and everything sounds so "cheap" like a video recorded on a old phone, tried to improve my mixing to fix it (EQ's. Compression..), but it keeps sounding "cheap".

Is there something that I am missing to improve my recordings or this is permanently coused because of the mic and without a better one I cant do nothing more?
