If we only consider the observable universe without the surrounding matter then yes, we are living in a black hole (which doesn't need a singularity.

For the Schwarzschild radius we have:

$$r_s=\frac{2GM}{c^2}$$

Filling in:

$$r_s=2*6,7*10^{-11}*10^{50}*9*{10}^{-16}=1,2*10^{23}(m)$$

Now the radius of the visible universe is

$$9,5*10^{15}*9*10^{10}=8,5*10^{26}(m)$$

From which it follows we are (under the unreal assumption that our visible universe is all there is) living inside a black hole.

Off course all the matter around the observable uUniverse prevent this black hole to really exist, and light rays can travel throughout the entire Universe (except off course if they meet a real black hole).

Now for M I only counted the non-dark matter neither the dark energy, which makes M in fact much bigger. Say 20 times. This makes $r_s=2,4*10^{27}(m)$.

Now the radius of the visible universe is. $$9,6*10^{15}*4,6*10^{10}=4,25*10^{26}(m)$$
