Senescent cells are only one factor in aging. You've also other mitochondrial DNA damage, accumulating nuclear DNA damage leading to cancer, gunk building up inside lysosomes, gunk building up elsewhere, etc. If I were to try to rank them senescent cells would probably be second or third on the list. Potentially a really big deal but not at all synonymous with aging in general. That is, if this actually pans out.
