It’s been a while since I’ve been annoyed by her this much:
The 12% annual average rate of return, which would make a Gen Z worker a millionaire before the age of retirement, is a conservative percentage, according to Orman, who estimates you can expect up to a 25% rate of return on your money.

Looking back on my history, I've only broken 25% in three years. 1999, 2009, and 2019.
I don't remember how good 1999 was in general, but I think I mostly lucked out with timing, dollar cost averaging, and the fact that I had so little invested in the first place, that lucky timing with an additional investment could make a notable difference. I was up 45% that year!
In 2009, I was up close to 45% again. Of course, the aftermath of a recession/serious market did will help you out a lot, if the percentage is all you care about. A Yahoo Finance writer might call it a "great year". I'd call it "almost being made whole again" after everything I lost in 2008.
2019 was similar. The market had tanked a bit at the end of 2018, bottoming out on Christmas Eve, so 2019 started near the bottom of that trough. That year I was up about 27%.
So, I guess Suzy Orman is right when you say you "can" make 25%. In the same vein, I recall an old Saturday Night Live skit where they talk about where monkeys might fly out of. I think I'd bet on the flying monkeys happening before any hopes of a consistent 25% return. Or even 12%, unless you're really lucky/talented.
