Thanks for reaching out to us. When using Excel or CSV files, this page has tips to help you format and work with those tables.
For formatting purposes, first I would remove the empty row at the top. Secondly, I noticed that the first two columns have the same name "tile". The software looks at the very first row in a csv for the column headings, so make sure it with no duplicates. Make those changes and it should work.
After looking at your table, you aren't actually geocoding, because that involves addresses. You have X & Y coordinates that need to be plotted. If your coordinates were in degrees, then it would not be hard to use the XY Table to Point tool to plot those points. You can still use that same tool, but since your coordinates are linear, then you need to find out what projection was used. I can tell your coordinates are not degrees because the XY numbers are so large.
Here is a short tutorial on using the tool mentioned above to create points from a csv table.
