Yes, but if all the other computers were using SMBv2 (at a minimum) how
could they 'talk' to the computer that only used SMBv1 and how could it
'talk' to them ?

Look at it this way, there are 20 people in a room, 19 only speak
English and one only speaks French (or any language that isn't a
variant of English), 19 people will understand each other, but the one
person that doesn't speak English will not understand the other 19 and
they will not understand the one.
