I’m having a hard time understanding this. From what I have read, a vacuum is a space that is devoid of matter. But there is matter in Space (planets, chemical compounds, stars, etc.). There is something I’m missing here and I’m not understanding

You can think of it this way. Space is a vacuum (mostly, there’s still bits of hydrogen and space dust floating about but it’s pretty close) and space contains planets and stars and stuff, but space itself isn’t made up of planets.
As an analogy a glass jar is made up of glass, and if you fill it with water the jar contains water, but you wouldn’t say that the water is part of the jar.
