Wdym by "inside Russian info" though.
-Invading Ukraine. This is something US could have straight up guessed based on the situation in the Donbass. Iran could make a prediction that US will invade China and it would have reasonable accuracy. That doesn't mean Iran has inside American info, only that Iran is capable of seeing where the wind is blowing.
-Lethal aid from China. Again, something that can be randomly guessed, given that China is already sharing anything short of actual whole weapons platforms, its not a big stretch to believe China would take the additional step. And China would not be secretive about it either, just like with the rest of its aid. So far, even this guess doesn't really pan out.
Besides that, they've also guessed a lot of random shit that didn't pan out, such as Russia running out of ammo, Putin being deposed, generals dying for supposedly failing only to magically return to life and recieve honors etc. almost as if they're just throwing out guesses based on the situation. When you've spent the entire year throwing darts randomly at the dartboard, you're bound to score at least a few hits right?
Russia probably has a bit of CIA in it just like the vice versa is true for US and the FSB, but on these topics specifically, no insider knowledge is needed to make a guess. In fact, multiple forumites here have made guesses of different forms of aid to Russia even earlier than Biden spoke up.
