A lot has happened with iPad and iOS in 7-9 years and in the past 2 to 3-1/2 years since iOS 9 and 10.
The 2019, 10.2 inch screen 7th gen iPads have a 1/2 inch larger retina screen, much faster and newer 2.3 Ghz, A10 Fusion processors, AT LEAST, 3-4 times the internal RAM, with the 2019, 7th gen iPad having 3 GBs of internal RAM, iPadOS 13 support, with much better and improved multitasking features, Apple Pencil and Apple Smart keyboard cover support and have better audio speakers and better/improved built-in cameras.
Amazon, itself, currently sells new, sealed in box, Apple's base model 2019, 7th gen, 10.2 inch screen, WiFi ONLY 32 and 128 GBs iPad models selling for $279 and $359, respectively, through its own direct sales distribution.
This is a $50-$70 savings from Apple's own pricing of these iPad models.
