You are talking about yourself. Pretty standard human behavior for the self doubter. It's called projection.
And I and tons of other growers have gotten fantastic results with seeds you did not.

Grown in horrible bagged potting mix with colorful label and terrible bottled hydro store nutes under awful indoor growing specific lighting.
And of course a low quality feminized seed. (Only one I have grown)
I must be really bad at learning stuff.
