There is no published limit. You are not going to hit any issues with 20 tables. If you are going to run 200-500 tables, then you may start to see real performance degredation, but Power Query is not going to throw up an alert and say "You cannot add anymore data sources"
I know of no practical limit. You also have to define what is a data source. If you mean Server and Database, then that is all the gateway uses. You can connect to 50 tables in Power BI from that same Server/Database combo. For Power BI that may be 50 data sources/tables (though I'd hope you merge them down to a useful Star Schema) but from the service standpoint, it is 1 data source and gateway connection because you don't define tables in the service, just servers and databases.
