If a guy knows you like him and acts normal - what would be your chances?

There was a guy from school that I had a very light crush on and I think he knows cause one time I gave him a compliment he thought he didn’t deserve and he was like, “(my name), don’t say that, please. I’m going to start blushing.” So I think he knew I liked him, it was a marginal crush, like 0.1% of my interest. Most of my crushes are around 5% to 20% of my interest.
