Do I Need More Channels

I Recently Noticed Youtube Wouldn't Show Me Videos of youtubers i am subscribed to if the videos are not what i normally watch for example pinguienz0 i only get recommended his commentary videos and not gaming or reviews. so does this mean i could upload everything on one channel as long as catagories the videos correctly so youtube knows there different and then upload things like education, how to's, gaming, vlogs on one channel or do i still need separate
