I just did some research on different types of BB and now im more confused with what is the compatible threaded BB for my crank.
Could someone shed some light on this? Thank you!

Isn’t the order of importance like: frame -> bb -> crank?
This is only half the question. You need to know what size hole you’re going into.
It’s _probably_ a BSA bottom brack, as you’re saying it’s threaded (though don’t take my word for it…T47 and Italian threaded are there as well). Careful measurement is key.
If it is a BSA-thread, and that is probably a 24mm crank axle, you’ll ant something like this.

BSA GXP
BSA is your frame interface (from your other comment). GXP is the crank interface. It’s written on the picture. I also have this crankset. And 80-90% of the AliExpress “cool looking” crankset are GXP
Are those two different cranks? First pic says GXP but second has a preload collar (DUB maybe?).
FWIW SRAM uses a steel spindle so I’d be leery of a company selling an aluminum spindle crank that’s missing a chainring bolt in their stock images
