ETA:
For accuracy, the chart is old (2014) and references discretionary spending instead of mandatory which is where programs like SNAP (Food Stamps) generally fall
However, even accounting for all that properly, at the time of the meme, food stamps would have still been just 2% of the federal budget. Thus the spirit of the meme is still good.
Social security and Medicare are considered mandatory spending. The chart above is presumably showing discretionary spending, which is a subset of the overall budget. I can’t speak to it’s accuracy beyond that.
