Ale przecież każda akcja ma swoje konsekwencje więc trochę nie rozumiem tego stwierdzenia "rezultat/wynik akcji w przeszłości"
That's true.Whatever has happened in the past produced some consequences that we recognize today.
But the present-day consequences of past events are (or almost always want to be) different from those that resulted immediately following the past occurrences. If you want to get back your interlocutor to the immediate past of a past event, use the past tense.
I can say "Gutenberg invented the art of printing." (This is a classic textbook example.)
I cannot say "Gutenberg has invented the art of printing." Why?
Let me try this for an answer: Because the results of his invention as seen by his contemporaries were entirely different from what they seem to us today.
Anyway, you have an inquiring mind, which is a good thing. Keep asking "why, why, why..."
