Poverty in S0201 vs B17001

Looking for clarification on the difference between the poverty estimates provided in tables S0201 and B17001, specifically for adults ages 65+.  Calculating by summing across sex and ages within B17001 yields pretty different estimates compared with the percentages given in S0201 at the state level. Is this a 'householder' vs member of household difference?

I'm comparing S0201's "Estimate!!POVERTY RATES FOR FAMILIES AND PEOPLE FOR WHOM POVERTY STATUS IS DETERMINED!!All people!!65 years and over" vs summing "Estimate!!Total!!Income in the past 12 months below poverty level!!Male!!65 to 74 years" variables across age and sex to get the total number of adults ages 65+ below poverty, over the total number of adults ages 65+ for whom poverty was calculated.
