Is the sigma 65mm f 2 dg contemporary good in low light?

The Sigma 65mm f/2 is a fast prime, and that's its main strength in low light. f/2 gathers far more light than a typical kit zoom, so you can keep your shutter speed up or your ISO down.

It's also made for full frame, and that's where low light really benefits. A bigger sensor gives you roughly a stop more than APS-C at the same framing and f-number, so what a bigger sensor buys you explains why it pairs well with this lens.

Keep in mind that this lens isn't stabilised, so in dim rooms you'll want to watch your shutter speed. For more on why primes suit this kind of shooting, see primes or zooms.
