Question

I have used bwa-mem2 index UCSC hg19.fa.gz file, but I have no idea about the output of this command. Does anyone know it? Thanks a lot!

Others may explain it, but I assure you that for the end user it does not matter. Just run the alignment and proceed with your analysis. The relevant output is the index files, not this stats printout.

OK, thank you! I just want to know more about the tool to optimize my resource usage.

I doubt that any index stats will help you with that. Don't overthink it, just run the analysis and you will see what memory usage it has.
