Kind of. There are pipelines and queues that data travels through before it is stored. At a high level, Universal Forwarders are only able to the input layer in that it will read the data and add some metadata to it (like index, sourcetype, source) and then send it to the indexer for the data to go through the rest of the process.
So, it's not that it has precedence or is higher priority, it just does that function because the Universal Forwarder can't. If you had a scenario where you were using a Heavy Forwarder, you could perform that functionality on the Heavy Forwarder and the configurations on the indexer wouldn't apply to the data at that point.
