The non-transcendental numbers (otherwise known as the **algebraic** numbers - Wikipedia link) comprise a _countably infinite_ set, whereas the transcendental numbers are _uncountably infinite_.
_(Why are there only countably many algebraic numbers? Because we can group them according to what polynomial in $\mathbb{Q}[x]$ they are a root of, and any such polynomial has finitely many roots, and there are only countably many such polynomials.)_
The point is: in colloquial terms, there are more transcendental numbers than algebraic numbers.
Therefore, there are certainly more transcendental numbers than there are algebraic numbers that also are not rational.
