They said its the same number though, not basically the same. The idea that as you keep adding 9s to 0.9 you reduce the difference, an infinite amount of 9s yields an infinitely small difference (i.e. no difference) seems sound to me. I think they’re spot on.
That’s what it means, though. For the function y=x, the limit as x approaches 1, y = 1. This is exactly what the comment of 0.99999… = 1 means. The difference is infinitely small. Infinitely small is zero. The difference is zero.
No, it’s not “so close so as to basically be the same number”. It is the same number.

No, there is no difference. Infitesimal or otherwise. They are the same number, able to be shown mathematically in a number of ways.

Infinity small is infinity small. Not zero
That’s simply not true, as I demonstrated in my example.
