agree with you on the concept of prudent risk management. But I cannot disagree more on your comments re probability. Everything in the market is about probabilities, exactly because what you said is true, inherently we all face uncertainty and there is no "always" or "never". But we can attach and attempt to fix probabilities to all possible outcomes. We will never reach perfection in measuring and estimating probabilities but we can do reasonably well. In fact whole branches of trading rely entirely on attaching probabilities to certain outcomes and factoring those into position taking and position sizing, e.g., options trading.
I have great respect for Bruce Kovner, but I believe he has been misunderstood in this quote. Charts are just a visualization of prices. I believe what he wanted to say is that even with a fundamental approach one needs to also take into account the actual price of an asset before investing in it. I do not believe that he attached any particular importance to charts vs price levels.

You could say the same about FA, stats, etc. Regardless of how you define "consistently." Whatever decision criteria you use, you will lose everything unless you incorporate meaningful risk control, because you cannot remove the randomness out of uncertainty. Forget "probability." That's more wishful thinking than fact in the markets. The markets are more about uncertainty, which is an opaque and distant cousin of probability, and requires greater allowances for error. So if you can find a means of occasionally catching a move while risking relatively little, who cares what it's called? But I think that, on balance, you'd be hard-pressed to do so without considering preceding market data, especially the immediately preceding market data, if you are to achieve anything resembling consistency and tightly controlled risk in some form.
Bruce Kovner, who relied heavily on FA, had this to say:
He also adroitly observed:
"Technical analysis, I think, has a great deal that is right and a great deal that is mumbo jumbo… There is a great deal of hype attached to technical analysis by some technicians who claim that it predicts the future. Technical analysis tracks the past; it does not predict the future. You have to use your own intelligence to draw conclusions about what the past activity of some traders may say about the future activity of other traders."
