There are around 12000 routes in the inet.3 table, quite far from 33431.

Solution

Starting in 22.4R3 and 23.4R1 Junos OS Evolved releases, the license counts only the Resource Reservation Protocol-Traffic Engineering (RSVP-TE) and Segment Routing Traffic Engineering (SR-TE) LSPs. Prior to the 22.4R3 and 23.4R1 Junos OS Evolved releases, license counts all Traffic Engineering (TE) such as RSVP-TE and SR-TE and non-TE such as LDP, BGP-LU, L-ISIS, L-OSPF LSPs.
[Release notes]

Before this change LSP scale license also included 6PE routes present on the system.
