all numbers are ideas.
and they are all nonsensical without a context.
on a very basic level, 1= stone, 1+1=2 stones, but this only makes sense if our unit of analysis is vague enough to disregard the weight dereference, chemical make-up, molecular count, and an myriad of other things. we adopt the idea that stone exists and represent it with a symbol of "1".
the fact that there can never be a second stone identical to the first doesn't matter because the concepts of "1" and "+" are so useful in helping us think and organise our thoughts of the universe. the same goes for the concept of infinity.
So in number sets, yes infinite means always growing cause we can always +1.
but are numbers infinite? NO, because eventually the universe and all time will cease to exist and so a number counting machine would reach the largest actual and finite number it could before vanishing.
or to baby step you to the concept, ask yourself if + exists?
