Good news, Alex. It is perfectly acceptable in English to call the thumb a finger (synonym for digit) and to call 0 a number, so that's two things that need no longer annoy you.
Also consider that when you let something annoy you that you cannot change, it has enslaved you. It can annoy you at any time and there is nothing that you can do about it. Relatively very few things irritate me, not because I have a strong character or gentle soul but because over the decades, I have learned the value of effective medication management.
