Terms = what you agree to when signing a contract
Conditions= contingencies for if the terms aren’t properly followed, usually some sort of penalty for breaking the rules, so the contract can continue without being voided or breached.
Basically, it is just legalese for saying that the product or service requires a contract or has an implied contract, and they are covering their bases legally by stating that what is in the contract applies to the good or service advertised.
