I am using a premade data set from a youtube tutorial video and it shows me FALSE, am I doing something wrong, which is resulting in the error of FALSE?

Code should be placed in three backticks as shown below

> all(colnames(counts_data)) %in% rownames(colData)
[1] FALSE
Warning message:
In all(colnames(counts_data)) :
  coercing argument of type 'character' to logical

Please understand that the support site is not intended to guide you through basics such as reading files (previous question) or matching objects from random (and not linked) sources. The DESeq2 vignette is the source to read and maybe the SummarizedExperiment docs which the DESeqDataSet is based on. Beyond that, use the many online tutorials on R basics.
