A number of things to consider regarding this survey (and the summarization in the article, which didn't evaluate the survey's approach).
1. The source is a used device marketplace. Hyping new product sales theoretically would be good for business -- since it would put more existing product into the resale channel. Not saying this is absolutely a conflict of interest in terms of the veracity of the study, but one should be aware when considering the source.
2. The survey itself references the 2020 SE sales as an indicator of what one would expect from the 2022 sales. The survey results note a CIRP study with the comment that 2020 SE sales represented nearly 25% of "all iPhone sales." If you look at that study however, you would see the figure is 22% (which is closer to 20 than 25) and more importantly, it was 22% of sales that particular quarter. Given the SE is launched off-cycle from the other flagship phones, it's not a surprise that it would see a spike in popularity specifically during the quarter of its launch -- and well into the existing sales cycle of the other devices.
3. What would be more pertinent is what % of sales does the SE represent of total annual iPhone sales. And one could argue that in that comparison, you would combine iPhone 12 with 13, 12 Pro with 13 Pro, etc., as they represent specific model types and price points that change during the year after which the SE is launched. But this point certainly can be debated, since often Apple leaves the prior mainstream device in the market (i.e., you can still buy an iPhone 11 today).
All that being said, it does appear the 2020 SE was a quite popular phone, and presumably the 2022 will be as well, as it will be the lowest-cost entry point into he iOS phone ecosystem -- and given Apple's history of supporting those devices for years post-introduction.
Just a reminder to apply some independent thinking to headlines you read and to get behind the numbers a bit.
