is this possible?

so... I was playing Bedwars with my friend Geodestrike....... first we went for yellow but guess what??? THEY ALL DISCONNECTED BEFORE WE GOT THERE. Then the blue team was eliminated by yellow... wait what? "Blues bed was destroyed by Simmon19902 （a player from yellow team）!" BUT BUT BUT YELLOW ALREADY DISCONNECTED! I was like whatever then I went to Green's bed and destroyed it. "Guy100234L_ fell into the void FINAL KILL! (A player from the green team)" the red team was eliminated by grey already... THEN "GRAYS BED WAS DESTROYED BY SIMMON19902!" wtf??? This simmon19902 is a hacker... then BED DESTROYED! "Geodestrike was blown up by Simmon19902!" So it was only me and this simmon19902.......... Welp, he was low on hp (5hp left) BUT HE REGENERATED HP AS FAST AS HE LOST HP! but then... I KNOCKED HIM INTO THE VOID! with a TNT when I had 1hp left. DUDE EXACTLY 1HP. not kidding... I reviewed the game and that simmon19902 guy was legit flying. I wondered why he didn't fly when I knocked him into the void. CONCLUSION! Sometimes hackers don't always win. Also, I reported him as well ofc
