The OP question is an interesting one and, having forgotten my previous posts in this thread, I think I will start from scratch again.
Chess is fundamentally a deterministic game. But firstly, if you are playing an imperfect player, there is uncertainty about whether they will blunder. So the action of them blundering is correctly viewed as "luck".
Even in the case the opponent plays predictably (say the opponent is a tablebase playing the alphabetically top move), a specific imperfect player has uncertainty about what will happen because they are unable to do a complete calculation, so uncertain if _they_ will blunder. Whether they do may be their responsibility, but it is still accurately described as luck.
The uncertainty being in the beliefs of a player, it is appropriate for them to have a probabilistic model of what will happen, either a precise one (eg based on the player Elos) or a rough one ("I have a 70% chance of winning from here").
Luck is no more and no less than the variation in outcomes within the uncertainty of a specific viewpoint.
So the answer is "yes".
Elroch is correct as usual.
But controversy about determinism versus fatalism continues on through the centuries anyway.
There's even a kind of controversy about fatalism 'determining'.
Its called Fate.
'As Fate has it'.
Isaac Asimov discussed the idea of 'future history' in some of his books.
Theories about determining the future.
With an idea that it would be impossible to determine the changing mosaic of small details.
But that it is possible to 'steer' events. Even in a large-scale way.
Realism: Nobody can know the future to an exact degree. Regardless of how much it might appear to be the case. Nor steer the future in a way that is both exact and all-encompassing.
And the present cannot be known thoroughly.
The past? Not all the details.

A random threshold that is somehow supposed to define luck according to you, with no explanation. I guess thats a reasonable way to refuse a logical discussion I attempted. Also I don't remember making a claim regarding the "amount of luck" like you suggest here.
Oh well, you accept a blitz game?
I don't play on chess.com anymore since I became more active on the forums and started getting challenges from trolls on a regular basis. I haven't really played anything but votechess here for many years. It's a lose-lose proposition. If I won, they'd just try to hound me on the forums.
If votechess were not rife with cheating, I would still play votechess which (on a good team that discusses every move) have by far the most satisfying and educational games of chess you can play here.
I agree with you on the latter point. I've found that those who control vote chess games play what THEY want to play much of the time. It's useless.
Regarding the former point, when I beat people in blitz or when I used to beat them in Daily, virtually no-one ever accused me of cheating. I've always blocked those who trash talked, in any case and maybe that's a tiny minority and I blocked them all, more or less. I don't think it's a problem except for someone to whom it may happen for some secondary reason?
