Google one is the paid tier of google for ordinary people, predicated on buying more storage. If you pay google to get more than the 15GB you are on google one and you've become a customer.
There are other forms of customer, GCP tenants, Google G-Suite, Google Workspace. If you pay google for these services, you get helpdesk directed at those services.
Google one includes your base google account. You can ask them about things unrelated to just having more storage, if it's within the compass of that level you paid for.
Google one has helped me when minor amounts of shit, a few clods short of "I lost my passkey" hit the proverbial fan.
