Difference between (Steam) Stats, and Leaderboards

Hello,

I can read steam achievements, and I saw UE4 has API’s for leaderboards.

What about stats? Steam defines (just things about the player) stats to be different than leaderboards (stats which are compared), although leaderboards are derived from stats.

Is there a UE4 API to set steam Stats, and not Leaderboard stats?

Thank you
