(If we stick to Mirriam-Webster again, here is what I found : to calculate or predict (some future event or condition) usually as a result of study and analysis of available pertinent data - i.e. - basically what I already told you a "prediction" is).
Oxford Learners Dictionary (because the Oxford English Dictionary is behind a paywall): "a statement that says what you think will happen; the act of making such a statement" https://www.oxfordlearnersdictionaries.com/us/definition/eng...
The current Wikipedia definition looks like a good fit for how I'm using the term here:
A prediction (Latin præ-, "before," and dictum, "something said"[1]) or forecast is a statement about a future event or about future data. Predictions are often, but not always, based upon experience or knowledge of forecasters. There is no universal agreement about the exact difference between "prediction" and "estimation"; different authors and disciplines ascribe different connotations. https://en.wikipedia.org/wiki/Prediction
No, that's merely guessing mate. Predictions are, at least in modern meaning, based on at least some data and some extrapolation model that more or less reliably predicts the development of your known dataset into future (uknown) values. I don't see you presenting either in your post, so that's not predicting, that's in the best of cases guessing, and in the worst of cases irresponsible distribution of Anthropic's propaganda.
