The draft selection rate for female players is only 30%, is the player pool poor??

Currently, there are 7 teams, and I heard they use one foreign player and up to two aqua players because the domestic players lack skill. Does the low selection rate for Korean players mean there are that many players who don't meet professional standards?
Watching the Wonder Dogs, it seems like many players are released quickly without even getting a chance. I was thinking it might be good if another team were added to create more opportunities.
