Yes
You can see a certain distance in all directions. Thus, you are in the centre.

Don't we just appear to be in the center?

No, you literally are at the centre
of your own observable universe. Think about it.
Nothing can travel faster than light. Nothing further away than a specific distance from you can ever possibly have any effect whatsoever on you, and is therefore irrelevant.
Speculation about anything beyond that range is pointless. It may as well not exist. It is an event horizon.

Of the observable universe, obviously.
Being the center of whatever is out there, no. We would have no way of looking at it.

objectively yes, subjectively no
i think is socks point, taking an egocentric view perhaps... but then you'd just get lost in quantum entanglement with jerry the belly button elf if you went looking for it... www.dailymotion.com/video/x4xj5oz

So wherever Socks is must be the center of the earth.
I once asked a surgeon, while in for abdominal surgery, if he would remove my navel. Sadly the answer was no.

no socks is the centre of socks' universe just as you are the centre of yours
universe in the true sense of the word, etymologically speaking, the universe you experienced before scientists came along to tell you it was otherwise.

In a universe whose dimensions are only constrained by the curvature of spacetime,
which originated from a single point and in which all points are expanding away from all other points, every point can be considered the centre.
You literally are the centre of the universe, because everywhere is.

Everything is expanding
Everything is going away from you, because spacetime itself is expanding. The further away stuff is,the faster it is expanding. We can observe that.
Now imagine something so far away that it is expanding at the speed of light. The distance to that point is exactly the same, in every direction - a sphere centred on you.
However, that's not the observable universe, because you can see some things that are outside of that area. If something just outside that sphere emits light, then that light is getting farther and farther away from you, but, your sphere is expanding over time, faster than light. At some point, the light will enter your observable sphere, so you can observe things beyond that boundary.
The observable universe is all the stuff that is within the area that light can travel in the roughly 14 billion years that the universe has existed.
It's roughly 100 billion light-years in diameter. You're in the middle.

Why is your sphere expanding faster than light? It's very definition is pinned to exactly the speed of light.

The universe can expand faster than c because it’s not actually moving.
Here’s a link to a Lawrence Krauss lecture that covers what we think we know about how the universe started, what happened next and how it’s likely to end*.
*Spoilers* We’re all fucked.

It's not stuff that's expanding, it's spacetime
The speed that things are moving away from you is proportional to distance, as spacetime expands. It can, and does, get faster than light as you get a long way away.
Veritasium can explain it.

I'm going to have to follow this up when I've had less beers. Which won't be tomorrow.

I think that video will explain, but ask if not
V is pretty good, despite the shirts. He posted a brief life-story a few days ago, which I found quite interesting. About how he got into his YouTubery.
