The astronmers calculate the age of the universe from the time it took for the light from the most distant objects to reach us. They need to include the time it took the universe to expand and carry that most distant object out to 13billlion light years. Once the expansion of the universe is included it should be added to the time it took for the light to be observed. The age of the universe is now calculated to be 35 billion.
The universe had to expand first.

Our picture of the universe is 13 billion years out of date. It always will be out of date even more so in the future.

The light returning accross expanding space is red shifted by the expansion. Light expansion in space is exactly equivalent to movement redshift.

The universe expanded carrying the galaxies out to 13 billion light years slower than light speed. The light emitted at that distance has to travel through expanding space for over billions of years. During its trip space grows by a large amount. So instead of having to traverse 13 billion light years there is even more space since the space has expanded.
The age of the universe is 44 billion years.

The universe is expanding slower than light this means that the most distant objects took more than light years time. It took 22 billion years for the universe to expand to what we see now at 13.7 billion LY distance.
What we don't see is what is ahead in time in the universe which is in the distance.
