You are not wrong but Jesus wasn’t against group prayer, he intended on building a church a few pages later
Matthew 16:18
And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it.
You should have referenced a couple of pages after that where he has something direct to say about preachers
Matthew 23:8-12
“But you are not to be called ‘Rabbi,’ for you have one Teacher, and you are all brothers. And do not call anyone on earth ‘father,’ for you have one Father, and he is in heaven. Nor are you to be called instructors, for you have one Instructor, the Messiah. The greatest among you will be your servant. For those who exalt themselves will be humbled, and those who humble themselves will be exalted.
Jesus had some pretty rad opinions even if his reasoning was often flaky
