Using

import plotly.express as px

print(px.data.__file__)

you can see path to source code and check it.

Digging in source code I found that on Linux data are in folder

/usr/local/lib/python3.7/dist-packages/plotly/package_data/datasets/

as .csv files compressed to .gz files so pandas.read_csv() can read it without problem.
And tips() uses pandas.read_csv() to read it.

You can display other functions in px.data which reads datasets using dir()

import plotly.express as px

for name in dir(px.data):
    if '__' not in name:
        print(name)

Result

absolute_import
carshare
election
gapminder
iris
tips
wind

Probably all of them (except absolute_import) are functions which reads some .gz file with data.

print(px.data.carshare())
print(px.data.election())
print(px.data.gapminder())
print(px.data.iris())
print(px.data.tips())
print(px.data.wind())

There are a few small dataset you can import from plotly.express.

When you write tips = px.data.tips() It’s import this data
