Yes, you need to be running at least version 11.1 of the Adobe Camera Raw plug-in to view the raw images direct from your Nikon Coolpix 1000.
The Photoshop Camera Raw 11.0 update (version 11.1) for Photoshop Elements 2019 was released in December 2018.
(Photoshop Elements 2020 and Photoshop Elements 2021 do not need updating as they ship with later versions of the Photoshop Camera Raw plug-in.)
If you are running Photoshop Elements 2018 or earlier, you won't be able to update to 11.0.
In that case, you can either download the Adobe DNG Converter which will convert your raw NEF files to the universal DNG format which you can then subsequently open in Camera Raw, or you might want to consider upgrading to Adobe Photoshop Elements 2021.
Here's a link to the Adobe DNG Converter if you need to go down that route:
