Use ax.bar_label:

import seaborn as sns
import matplotlib.pyplot as plt

# Load sample
titanic = sns.load_dataset("titanic")
ax = sns.countplot(x="class", data=titanic)

ax.bar_label(ax.containers[0], label_type='edge')
plt.show()

What is your version of matplotlib? Here 3.4.3. – Corralien Dec 09 '21 at 22:45
3.3.4 is my version of matplotlib – bony767 Dec 09 '21 at 22:47
You need a version >= [3.4.0](https://matplotlib.org/3.4.0/users/whats_new.html#new-automatic-labeling-for-bar-charts). Is it possible for you? – Corralien Dec 09 '21 at 22:48

Using `fontsize=10` and all available parameters for [`Text`](https://matplotlib.org/stable/api/text_api.html#matplotlib.text.Text) – Corralien Dec 09 '21 at 23:02
