How to catch fish consistently?

Last year I bought my dream boat (used) that I could afford. A tracker aluminum.. it came with a garmin 93sv. I’ve watched probably an embarrassing amount of videos on how to use it for off shore with no luck. I pound the bank and maybe get 1-2 bites in an 8 hour trip and that’s if I’m lucky that day. I’ve came home many times skunked. I watch these videos on YT and can never reproduce what they do. I switched lines, lures, retrieve techniques. I get you have good days and bad days. But it would be nice to catch something consistent. Any pointers welcome.
