That's right. The spread of shifting all the blame for one's actions and decisions to someone else is a very common phenomenon, and even as a rule, a player rarely blames only himself for losing. But in the case of winning, of course, on the contrary, he immediately begins to forget those who advised him to place such a bet and extols his own decision, which turned out to be correct and brought victory. Apparently, such behavior of a person is connected with his usually unsatisfied ego or with the fact that every person always wants to look like a winner in the eyes of other people, smart, calculating and brave. And no one wants to seem like a loser to others. This is the reason why people often remove the blame from themselves for wrong actions, in this case, for wrong bets.
It's true, I have accidentally made small experiments in some things, not in games of chance, but in mistakes that I have had in certain activities and I have shared them with some people, and they always put on a face of "if it were me, I would not have made a mistake" but I am very sure that they would have made mistakes there and in more things, but most people like to hear or see hypocritical answers, even here in the forum, sometimes those who are sincere do not like some Users, and I assume that nobody is perfect, that we must assume our mistakes and it is part of our learning and more in casinos.
Of course, admitting your mistakes is a direct way to learn from these mistakes and not repeat them later. This definitely applies to all people who gamble. And this is obvious and is a set of player experience and improving the skills and style of your game. And this path of mistakes is different for everyone and it is original, unique.
Therefore, the advice of any advisers who are sure that they would have acted differently in some game and, as they believe, more correctly than you, most likely should simply be ignored. And at the same time, you should not think badly and hold a grudge against such advisers, but it is worth keeping in mind that sometimes their advice is useful, but sometimes these tips are intended by them to harm you or somehow complicate the game. Even if they themselves do not participate in the game itself and are third-party observers. Often, they are driven to such negative actions by simple human envy.
