Welcome to the High School Baseball Web! ...and congratulations for having made all-league!
Assuming that playing baseball in college is your goal, here are a few "quick hits" to supplement the good advice you've already been given by RJM:
(1) Don't let a day go by that you don't do something to advance your game and your performance in the classroom. Those two dimensions will have much more to do with your reaching your goal than anything else.
(2) Put yourself in position to play the best competition available by selecting a summer/fall team that's appropriate to your recruiting process.
(2) Invest time and effort in figuring out what sort of college appeals most to you and what level of baseball program best suits your playing ability. Read and talk to credible resources about the differences among colleges of interest. Solicit evaluations of your playing ability from highly knowledgeable, credible baseball people in your area.
(3) Once you've begun to build a list of pertinent schools/programs, find out where they evaluate prospects. Which showcases do they attend regularly? Do they recruit from their camps?
(4) Let pertinent programs' coaches know of your interest. Email a fact sheet and summer/fall schedule to them. Let them know when you'll appear in a showcase or tournament that you think they'll attend.
To your specific question: Only the organizers of the showcase that invited you can give you a meaningful answer to your question; but, it certainly wouldn't hurt to email them, tell them that an unavoidable conflict prevented you from attending, and tell them how very interested you'd be in attending another of their showcases in the future.
This should get you headed farther down the path. Stay close to this site for additional insight and advice; taking advantage of pages like the

Best of luck to you!
