There is an infinite number of non-zero numbers. Not even considering negatvie and irrational/imaginary numbers, if you give me any positive number, I can give you another one by simply adding one to it. No matter how large of a positive number you give me I can always give you back a number that is one number larger.

There is an infinite number of real numbers. The irrational numbers can be put in correspondence with all real numbers. So in some sense there are as many real numbers as irrational numbers. They have cardinality aleph 1.
The same can be said about negative numbers: there are as many negative numbers as positive numbers and as many as all real numbers.
But we can't say the same about rational numbers, they are still an infinite number but, in some sense, a "smaller" infinity than irrational numbers. The rational numbers like natural numbers have cardinality aleph 0.
