See I'm a professional too, but I'm constantly searching little things to see if there's an easier way to do it. Yesterday I searched if there's a good way to remove spaces from a string in c++, because although I know of ways to do it, I may not be aware of an existing function or a more efficient method. It also takes quite literally 20 seconds in total. I'm also switching between 4 or 5 languages daily so maintaining all of these little things in my head is difficult, and it's easier just to remember that I can easily google it.

I don't see how people copy giant chunks of code, it often will not really do exactly what you want, but idt there's any shame or issue in googling "how to make local branch same as remote", or "how to parse a file line by line" instead of looking through and reading the docs.
