That's the right attitude. The most important question is... am I competent with a firearm in defending myself? I'll be intentionally over dramatic in stating that half the guys who win at matches would piss their pants in a real defensive shooting situation. Or get shot first.
Target shooting in all of its incarnations is good practice but it in no way duplicates defensive shooting. Certain IDPA matches get closer, but sadly in my experience, too many guys who are tools that imagine themselves as Olympic shooters or officials have invaded the ranks and ruined it.
I played a lot of paintball once upon a time (before compressed air guns, when all was CO2) that is about the limit of my experience, so yeah, I would get shot first, might get one or two good shots off in the process Doesn't help that I am a sasquatch and can't ever find anything big enough to hide behind
I do not equate matches to any sort of defense shooting. I do practice on my own how fast I can pull from my holster and get a double tap on target (without shooting myself in the process).
