how can this be interpreted?

Hello guys,,I have searched for a term on Google Keyword planner, and it showed a result of (1M-10M ) average monthly search value, without any other keyword suggestions. But, When I tried to lookup for the same term on Ahrefs and other SEO tools, there were no results as if that keyword has a very low search volume so that it's not appearing on Ahrefs? the same thing happened when I searched for the term on google trends ...So, it seems to me that the search volume estimated by GKP is way far of being true...the question now,,, can google give a so wrong value for the avg search volume? what are your thoughts?
