ELI5: If it took 13.3 billion years for light to reach Earth from the furthest known Galaxy, could it be possible that there are other galaxies further away than 13.3bly, but we just haven't been able to see yet because its light hasn't reached us yet?

What you've described is the case, according to the standard big bang model. The (potentially terrifying) thing is that we will never see beyond this 'horizon' because space itself is expanding, meaning that everything beyond that horizon is moving away from us faster than the speed of light. So we will actually only be able to see less in the future.
