Depending on the value assigned to the position property yes.
To position any element there are other properties which can be used too, like left, right, top and bottom.
The position property just sets the type of positioning. Take the example of the navigation bar of this particular website.
If you use the Inspect Element command you will find the position property is assigned fixed. What fixed does is it sticks to the element to the viewport. The divs will stick to the screen at that place even if the page is scrolled, in this case the top of the screen.
Now if you changed it to relative, it will stay at the top and will disappear if you scroll down. Add 50 px to the top and it will leave a 50 px gap at the top and all elements of the page move down 50px. Which is what relative does. It positions the element relative to the top, bottom, left or right of where it is was placed when all other positioning values are 0.
If you change it to static, it just stays at the top where it was originally set when creating the HTML document. But try adding other positioning properties to it like top, bottom, left or right and it wouldn’t move. Static is not affected by those properties.
For absolute, the element is positioned relative to the nearest positioned ancestor. Since the navigation bar has no ancestor, it just stays at the top. But if you add a top 50px to it, it will overlap with the elements below it and not move everything down by 50 px like what happens in relative.

Also, use the inspect element feature or the css inspector extension on Chrome to play around with the html and css if you have doubts. Nothing clears a concept better than applying it yourself.
Hope this helps.
