No, the size of infinities vary! Some are smaller than others.
Eg: the size of the set of numbers between 0 and 1 is infinite (0.1,0.11 and so on), but the size of this infinity is different from the size of the set of all numbers.
This is very very complicated maths and even the greatest mathematicians have avoided this paradox.
I don't know the proof well so just search around the net for it.
In mathematics, there are at least two categories of infinite sets - countably infinite, and uncountably infinite. Countably infinite means that you can set up a one to one correspondence between all members of the set and the set of natural number, aka "counting numbers".
Integers are countably infinite. You can pair them up with the natural numbers thus: 1,0 2,-1 3,1 4,-2 5,2 6,-3 and so on. The set of even numbers, odd number, and rational numbers are all countably infinite. The set of Real numbers, however is uncountably infinite. It can be shown that you can identify at least one real number that is not included in the set when you try to count all real numbers - thus while there are an infinite number of integers, there are even MORE real numbers. Not all infinite sets have the same number of elements.
In mathematics, two common types of sets are finite sets and infinite sets. A finite set contains a limited number of elements that can be counted, such as A = 8. An infinite set has an unlimited number of elements, such as the set of natural numbers . Sets are an important part of mathematics because they help organise numbers and objects into groups. The type of set depends on the number of elements it contains.
A finite set, with n elements has 2n subsets, including the empty set and itself. For infinite sets the number of subsets is the same order of infinity.
A finite set is one containing a finite number of distinct elements. The elements can be put into a 1-to-1 relationship with a proper subset of counting numbers. An infinite set is one which contains an infinite number of elements.
Two sets are considered equivalent when they contain the same number of elements, regardless of whether the elements themselves are the same or the order in which they are listed. This means there exists a one-to-one correspondence (bijective function) between the elements of the two sets. It’s important to note that equivalent sets can be of different types, such as finite and infinite sets, as long as their cardinalities match.
Cardinality refers to the number of elements in a set and can be categorized into several types: Finite Cardinality: Sets with a countable number of elements, such as the set of integers or the set of colors in a rainbow. Infinite Cardinality: Sets that have an unbounded number of elements, which can be further divided into countably infinite (like the set of natural numbers) and uncountably infinite (like the set of real numbers). Equal Cardinality: When two sets have the same number of elements, demonstrating a one-to-one correspondence between them. Understanding these types helps in set theory and various applications in mathematics and computer science.
Finite, countably infinite and uncountably infinite.
The cardinality of finite sets are the number of elements included in them however, union of infinite sets can be different as it includes the matching of two different sets one by one and finding a solution by matching the same amount of elements in those sets.

One possible classification is finite, countably infinite and uncountably infinite.

Two sets that contain the same number of elements are called "equinumerous" or "equipollent."
Equivalent sets are sets with exactly the same number of elements.
Two sets with the same number of elements are called "equinumerous" or "equipollent." This means there is a one-to-one correspondence between the elements of the two sets, allowing for a direct pairing without any leftover elements in either set. If the sets are finite, they have the same cardinality, which is the term used to describe the number of elements in a set.
