How does the Ontario Draw work?

Dear, Community.

Can you please let me know how does Ontario Draw work? The reason I am asking this query is that on 13 May 2020, there was a draw and the minimum CRS score was between 421 and 451; I stand in the EE pool with 461 points. Forgive my ignorance, but I was under the impression that this should have given me an opportunity for ITA, and the draw was for Technical professionals.

What are the various constraints that decide the ITA? I apologise if this is really a broad query.

Thank You.

This draw was only for canada work exp class.

Thank You, Sir.

I think I need to wait for 5 more months to get that 1 year of Canada experience under my belt.

Thank You.
