I find bike tire and tubes sizes quite confusing. I currently have a road bike whose tires are 27"

I was told that I could get a tire that was 700x 1 1/4
But all I am seeing is 700x23 - could I use these tires? And what is the difference between the 23 and the 1 1/4 anyway? Sorry so sound like an idiot but, while I love riding my bike, I'm just starting to learn the technical side of things.
