i think yes. tried test data:

for d in yourdata     let leaguelist = d.livescore.league     league in leaguelist         let eventlist = league.match.events         filter !is_null(eventlist)          let eventlist2 = eventlist.event         event in eventlist2             filter event._playerid == "2405930"             return event

of course not sure if understand data modell / problem correctly, maybe example helps you.
