Yes, aleph numbers are so big that even considering them as a set leads to a contradiction. This is called the Burali-Forti paradox

https://en.wikipedia.org/wiki/Burali-Forti_paradox

It means that aleph numbers form a "proper class". That is a class, which is not a set. I'm pretty sure that implies them being bigger than any set, but that we also can't define their size.

There are many answers regarding this on stackexchange:
