In addition to Artur's answer,
When you restore a DB it uses a fill factor to only fill pages to 80%. This
means that you have 20% space in each page before having to spill onto other
pages. So if you have an empty DB and just insert, you will end up with
100% fill of each page. There is an option to use full fill factor if you
want, but I wouldn't as updates will perform poorly.
