In my understanding there are two types of trading, which are NOT-guessing. First - HFT, which is really about technology, artificial intelligence, data science, etc. Second one is long-term investment, which also can be predicted with pretty high probability. Everything else sound like a magic and don't work (imho).
I don't think artificial intelligence has anything to do with HFT trading
HFT trading is basically an implementation of a "hit and run" approach, and the one who can hit harder and run faster gets an advantage. The rent rates on the blocks around major exchanges are skyrocketing because many big time traders are minimizing delays to reach to the exchange, and the HFT algos used should be pretty simple to be fast enough to receive and send orders real-time with minimal delays. Basically, they are just looking for small arbitrage opportunities due to market inefficiencies. So it is unlikely that AI is somehow involved in all this. It would be too slow in comparison with polished algos
