Correct. It was. Rosenbaum had already threatened that he would kill him and Ryan Balch if he caught either of them alone, according to Balch's testimony. The street level footage, drone footage and FBI footage showed that Rittenhouse turned up at 63rd street, and was ambushed by him immediately.
Ask yourself why it was only Kyle. Why only Kyle? Why not the others with guns?
One theory is that Rosenbaum may have mistakenly identified Rittenhouse as this similarly dressed and equipped individual, who Rosenbaum had tried to fight at the gas station earlier and had to be restrained.
Opportunity. None of the others got caught alone like Rittenhouse did. It was just one of those fateful encounters. Bad luck, even. Incidentally, Rosenbaum had already tried to fight the armed people at the gas station when they extinguished his dumpster fire that he was pushing toward it.
