Hi,
the same answer as given in the thread below should be valid here as well.
Unfortunately this is a question no one can answer you without having knowledge of / deep insights into your scanned environment. The amount of results for a scan highly depends on various factors like:
- exposed and identified services, applications
- existing vulnerabilities within this services/applications
- coverage of 1. and 2. within the feed
- the chosen port list (e.g. All TCP vs. nmap top 1000) assigned to your task / target
