Pi as a number in and of it self, and pi when plugged into the process of writing out all its digits into symbols humans can use, which is called decimal expansion, is absolutely not the same and it only makes you a midwit Dunning-Kruger by revealing that you don't know any of this.
You can't prove the existance of something by hand-waving about "infinity". You're making a very specific claim, which is that pi's expansion contains every finite sequence of digits (or characters in your case) and this has not been proven for pi. It cannot be accepted just because pi's expansion is infinite, you would actually have to show it. But if you respond "Well duh, that would be impossible!" then that's the point: if can't be converted into something meaningfully tangible then it quite simply has no meaning.
You have to distinguish between the general notion that "there are infinitely many possible finite strings" from the nontrivial claim that "every one of those strings appears as a contiguous block in this particular infinite sequence". That latter is a precise, and nontrivial statement that requires proof or a construtive method to demonstrate the occurances.
