It depends on what do we call a prediction. If we expect that AI will give a 100% answer about what will be in the future then it is impossible, at least as modern science know. But if we talk about statistical probability of different main variants I guess it can do so. But if to choose most probable variant all the time you'll get an error anyway as events with low probability happen as well and relying too much on an AI advice can end with total loss. So right, it is important to understand for any tool how it works and not expecting it can do more that it can.
That is all it can do anyway, and yes it could be wrong. It will have all the data that you could have, of course it can process it a lot better and give a much better result, so the answer could be "it can be better trader than I could be" is true, that's not really wrong, but the fact that people expect it to be right all the time is just not understanding the market.
If you know about the market, you know that even the most likely things may fail and when you expect something, just the opposite could happen. Even if we are talking about just a bad news which could change everything. Which is why AI could be better than me, but not without its faults.
