Can I get paid to take care of my Mom if she has Medicare and Tricare?

Medicare and Tricare are NOT set up to pay for private family caregivers at home. Some states have Medicaid programs with waiver that will pay some (not 24/7) care at home by family members. Some veterans or surviving spouses qualify for Aid & Attendance which can pay family members in certain circumstances. Of course, your parent can always privately pay you but that didn't sound like what you were asking.
