Buddhist monk education level
The main objective of being a monk is to attain Nibbana as soon as possible. Not to achieve recognition for being knowledgeable or intelligent. Read the story of the novice Culapantaka who couldn't even memorize 1 stanza for 4 months.

I went to: 1-6 primary school 7-9 secondary school Is this enough to
become a monk?

Being capable enough to chase away a crow is enough to be ordained as a novice. So, yes!
Keep in mind that you don't have to make youtube videos or preach to large audiences, just because you get ordained. You could simply stay in a forest or monastery, meditating. Wanting to be recognized can cause a lot of depression in a person. Work on giving up that need.
