You're right. But to me, sparring is considered competing.
You are matching up with your peers of the same level/caliber from a gym perspective or amateur level or even professional. To me sparring is competition of skill.
Not sure what you consider rolling with your peers? Practice? IDK... To me that's competing but I"m not knowledgeable in that jujitsu terminology as you are or my 13 year old lol... He does love it, tho. It's also helped him with wrestling as he's last seasons section 9 & state champ for his school district in his weight class. Proud dad moment lol.
