The top plot has default x-axis and y-axis ticks, text, and title. To remove axis labels altogether the bottom plot adds a layer to set the axis ticks, text, and title to ggplot2::element_blank() which is used to draw nothing and to take no space within a non-data component of the plot, using the ggplot2::theme() system:

Notice the use of dplyr::sample_frac() to plot a 20% random sample of the dataset and thus the actual points plotted in the two plots above are randomly different.
