How likely is it that I can catch an earlier flight on standby?

It’s a LONG story why I have to catch an earlier flight. I already spent a lot of money on my plane tickets….

Anyways, my plane is supposed to leave on July 16th at 10:00pm. I’m flying with Delta Airline. I’ll most likely be at the airport in the EARLY morning…earlier than 10am.

Is there a chance I can get on an earlier flight than 10pm? I’m flying from Los Angeles to Columbus, OH and I do know a lot of flights fly out from LA

I have one checked baggage so I think that might hinder me.
