Following the installation guide, I have installed atoti library:

(atoti) C:\Users>conda list
# packages in environment at C:\Apps\miniconda3\envs\atoti:
#
# Name                    Version                   Build  Channel
abseil-cpp                20200225.2           ha925a31_2    conda-forge
aplus                     0.11.0                   pypi_0    pypi
appdirs                   1.4.3                      py_1    conda-forge

atoti                     0.4.3                   9238575    https://conda.atoti.io
attrs                     20.1.0             pyh9f0ad1d_0    conda-forge
...

I have also downloaded the Pnl Explained notebook from atoti's github and I am trying to read a file on s3:

position_sensitivity_store = session.read_csv(
    "https://data.atoti.io/notebooks/pnl-explained/position_sensitivities.csv",
    keys=["book_id", "instrument_code", "currency", "curve", "tenor"],
    store_name="Position Sensitivities Store",
)

I encountered the below exception:

OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: 'https:\\data.atoti.io\\notebooks\\pnl-explained\\position_sensitivities.csv'

I am able to access the file directly from the browser. How can I load the source files into atoti? Do I need additional libraries to read the source files on S3?

To load S3 data, you need to use the scheme s3, as shown in the new version of the notebook:

position_sensitivity_store = session.read_csv(
    "s3://data.atoti.io/notebooks/pnl-explained/position_sensitivities.csv",
    keys=["book_id", "instrument_code", "currency", "curve", "tenor"],
    store_name="Position Sensitivities Store",
)

See this page [1] for complete reference.

Because you point to data provided by the notebook, as the notebook was moved - according to the new document at the end of your link - I suspect that the data it uses was also moved somewhere else. BTW, it is now here [2].
