Adjusted stats in NO way are saying that Gretzky wouldn't be equally as dominant in today's NHL. That's straight up false. See my analysis below.
For example: Let's compare Gretzky's dominance in his 92 goal season and try to adjust it to a DPE 2.0 season (2015).

What adjusting for stats IS: Having the common sense to understand that league-wide scoring has changed significantly over decades, and that comparing raw stats from very different environments is not very meaningful without this context (just like comparing someone with a net worth of $1,000,000 in 1980 is not even remotely the same as in 2020).
-> It is saying that Gretzky statistically wouldn't score 92 goals if his peak season was in 2015 (due to the significantly lower scoring LEAGUE-WIDE environment). But it IS saying, Gretzky would likely have scored around ~62 goals given the exact same goalscoring dominance. And that on a RELATIVE basis, 62 goals in the 2015 NHL = 92 goals in the 1982 NHL.
Ignoring the difference in league-wide scoring (and refusing to look at things on a RELATIVE basis) would then lead you to the conclusion that peak Gretzky would be TWICE as dominant in the 2015 NHL as he was in the 1982 NHL (by assuming that he would still score 92 goals despite the significantly lower scoring environment - leading to double the dominance over his peers).

THIS ^ is a terrible argument, and perfectly illustrates why adjusting for stats is important.
