I tried googling this, but I couldn’t understand what it meant, so can anyone here help me out?

You can see Mercury, Venus, Mars, Jupiter, and Saturn with your naked eye. Jupiter and Saturn are always farther away from us them the sun.
I suspect Mars and perhaps Venus can be visible when they are farther than the sun from us but I am not sure.
The requirement for us to see them that they are up in the sky for us during the night.
The planet does not emit light by itself but only reflect sunlight. Because of their distance from the sun and us and their size, they will be a lot less bright than the sun.
Out atmosphere scatters sunlight so the sky is blue during the day. For us to see something in the sky it is to be brighter than the sky. It is only the moon that is brighter than the sky so it can be visible during the day. The planers in the solar system simply are to dim to see.
There have been supernova and even reflection from satellites that was visible during the day but nothing except that moon and of course the sun in a normal situation.
You can compare it if it is dark outside and you look at a window. If you have a lamp on the inside some light is reflected in the window. You can still see a very bright light through the window but not a dim light.
When you turn off the lamp indoors you can see a lot of dimmer light outside.
You cant see Uranus or Neptunus with you make eye because they are too dim. Just like as you can’t see a cable very far away even if there is nothing between you and it.
