Badly worded, since "number" is ambiguous in this context.You should have said "the infinity of all real numbers is larger than the infinity of prime numbers"
"more infinite" is not correct mathspeak.
Note that the infinity of prime numbers is the same size as (in the jargon, can be placed in one-to-one correspondence with) the infinity of prime numbers, which is equal to the infinity of integers, which is equal to the infinity of algebraic numbers, which is NOT equal to the infinity of real numbers.
