When talking about funding in general, you also have to consider that SpaceX has significant non launch Equity funding to the tune of $10B, and that contracts can include potential future Revenue instead of funds received.
Edit: If you look at their launches for 2020 onwards[1], Their number 1 customer is SpaceX (themselves), followed by US and other governments, followed by private companies.

While your borader conclusion is probably accurate regarding income, your spreadsheet only 71 of 216 Falcon 9 and Falcon Heavy launches, for ~$9B total. This is roughly on par with the VC funding they have recieved.
