wire question: replace an old ceiling light

so I opened up an old ceiling light, and

There are 4 sets of wires in the wire box, three of them have 3 wires(white, black, ground), and one has 4(white, black, ground, and red)

*All 4 ground wires are capped together.
*All 4 black wires are capped together.
*All 4 white wires are capped together, with a new one coming out of the cap to the old light.
*The red wire goes to the old light.

So basically the old light has only a red and a white wire, no ground, it that right?

I am going to install a new light, should I still use the red, white, and connect the ground this time?

The fact it worked is proof that is the correct way.

ground wire should be connected with ground wire of new light as well.
if you have a metal junction box, ground wire should be bonded (screwed) to the junction box as well.

If the new light fixture comes with a ground wire (probably a green wire), that should be connected to the grounds.

Fixtures and appliances only have grounds if they are metal.

Your old light fixture probably did not have a ground. Was it a porcelain or plastic light bulb base?
