How to create a large fake database for app development?

Question

Database

For development, I need a decent database of several thousand (tens, hundreds of thousands) user profiles. It will be a dating service and each user will have many different characteristics. Before launching the service, you need to test the algorithm for selecting user pairs.
I know that there are services that make it possible to create a fake api with a pre-prepared response.
For my purposes, I need such a service to provide not one fixed version of the data per request, but a bunch of options. That is, if there are 10 characteristics in the user profile (not counting the first and last names), each of which contains 4 options, then the number of non-repeating user profiles is 4n10 = 1,048,576
Is there an api service that can generate a fake database from the provided parameters and their options?
I will have enough base for 10-50t. records.
