The key gtfs:trip_id:sample=* is used in public transportation tagging to add one trip_id from the GTFS trips.txt file as example to a PTv2 type=route relation.

Please, use gtfs:shape_id=* if present in trips.txt or shapes.txt as it better fits.

gtfs:trip_id:sample=* is evaluated by PTNA to link from the analysis to the GTFS data if additionally gtfs:feed=*, operator:guid=* or network:guid=* (in this order) is present (example).
Adding the gtfs:route_id=* does not harm but is not needed as it is derivable from gtfs:trip_id:sample=*

If the route variant represents only one trip with a single service_id gtfs:trip_id=* is an alternative key to use.

Two different name spaces

Currently, two different name spaces are used for GTFS, gtfs_* and gtfs:*:

gtfs_trip_id:sample=* gtfs:trip_id:sample=*
