The sharpshooter fallacy is where you pick the target after the shots are fired. In this instance, the "target" is you existing. Since you already existed when you set this target, it is absolutely by definition the Texas Sharpshooter fallacy.
Picture if we were playing cards. You got four aces, and I got a six of diamonds, a jack of clubs, a three of clubs, and a seven of hearts. Then I pull out some paper and write "RULES: Aces are worthless, and if you have a six of diamonds, a jack of clubs, a three of clubs, and a seven of hearts then you win" on it. Now I say that I get to take all your money, even though I wrote the rules after we already drew our cards. Would you be okay with that? (Note that both our hands have equal likelihood - the only reason to value one over the other is because of the rules we've made up whether that's my newly-written rules or the more common rules of, say, poker.)
