That is definitely true. And poker theory also evolves over time. The first training videos, I watched, were those made by Splitsuit for The Poker Bank, and they are now seriously outdated. Solvers in particular have created a whole new level of understanding of optimal (unexploitable) strategy, which just did not excist 10 years ago.Learning poker is a marathon not a sprint. There is a saying that goes something like "it takes a minute to learn and a lifetime to master" and I can't think of many more examples where that is truer than in poker.
I actually think, watching a final table can be a reasonable way to study. The reason is, that you usually get to see an unedited version of the action, and everyone are doing their best to play well. However if you then see the pro do something different, from what you would have done, then you need to watch training videos or read articles to try and find out why. And of course also understand, that a final table is played different from other phases of the tournament.As humans, we tend to look for the easy option or the quick fix. When it comes to studying, we kid ourselves that watching a twitch stream or high roller final table on PokerGo is studying, which unless you are truly focused how a pro plays a certain spot, this is really about as much use as watching a film or football match.
I agree with you, but my point here is to do with the focus of what you are watching. If you are really paying attention, making notes and trying to understand why the pros are making the plays they do, then yes, it can be useful. But I doubt there are many amateurs watching FT's that are really doing this in any meaningful way.I actually think, watching a final table can be a reasonable way to study.
