From Toby Ord's The Edges of Our Universe:

• The expansion of space will prevent us from ever affecting 95% of the galaxies we can currently observe.
• However, our "affectable universe" still contains about 20 billion galaxies, housing at least 10²¹ stars.

Divided equally among Earth's 10 billion people, each person's share of this cosmic endowment would be 100 billion stars.

To count your share, you would need to count by 31 each second for over a century:
