CSPRNGs still need to be seeded with random numbers.

And very importantly, a TRNG is often not cryptographically safe and should never be directly used for security related use cases. Basically only be used to (re)seed a good CSPRNG (DRBG in NIST parlance).

Another benefit of a CSPRNG is vastly higher performance than most TRNGs can achieve. A TRNG often provide kbps birate. A CSPRNG can easily deliver Many MBps, even GBps.

thank you.
