standardization
from the lesson I got that in the standardization process we transform the mean and the variance of a dataset to be 0, 1 respectively, but 0:20 does not say that.
So can you clarify it to me, please?

I think what you are trying to say is that you don't see the relation between transforming the mean and standard deviation to (0, 1) respectively, and the formula "(x - mean)/standard deviation".
the idea is that for each datapoint "x" in the data set you will apply the formula which result in a standarized version of that value, all these values together form a new dataset that produces a standard normal distribution.
i hope this helps!
