comment What does it mean when a statistician says I’m 90% confident that the mean of the population is between 1 and 9?
how about this: It means if repeated samples were taken from the population and a mean computed for each samples, 90% of the samples would include the unknown mean between 1 and 9.

how is this interval useful to us? I can only make the claim that I'm pretty sure that the population mean is between 1 and 9

can you turn around and say that 90% of the samples of size n have a mean between 1 and 9?
