All streamers say the same thing: push everything, that's how you git gud. And I will back your unpopular opinion by saying also that they are wrong. They might be right for a very specific kind of player - a player like themselves who is already preternaturally good at shooters in general and who is on a one-way grind to predator. But that's less than 1% of players. Normal people like us? The cynic in me says that streamers say "drop hot always and push fights to learn" in order to have idiots to shoot at when they're mowing down silver lobbies on their latest secondary.
But whoever learned anything by smashing their head against a brick wall? No, gun mechanics are not the first thing to learn in battle royale, and when it IS time to learn them then you find a way that doesn't involve just giving over thousands of free kills to streamers, pros, and cheaters. And yes, I'm lumping all three in as one, not making a list.
The problem, of course, with "never push a bad fight - ever" is that most new players couldn't tell a good fight from a bad one. Heck, most normal, average, EXPERIENCED players struggle with this. I may not be able to hit the broad side of a barn with an automatic in this game, but I know EXACTLY where to drop, when to move, where to go, how to get there unmolested, AND when to avoid a fight and when to take one. If only gun mechanics were as easy as everything else. If only most normal players understood that this game is a lot more than just gun mechanics.
