Is this real?

If your highest difficulty is not over 134T, then your Bitaxe didn’t find a block. It is common glitch if you are are mining on Braiins pool I believe.

First time I see it or hear from this glitch. Does everyone get to see this popup or just random people? Braiins did find two blocks within 24h but that's not special at all, happens all the time

I don’t think too many people use Braiins with open-source home miners. Most do solo. But I have seen multiple people being confused about this pop-up.

You are solo mining or pool?, check the difficulty
