Not necessarily. Everything sort of stretches at the same rate cogs, chain, etc, until the chain will jump (not jump off- like yours) but jump and skip a tooth or two when you put the hammer down. Usually it's in the gear ratio you use most.
Very annoying.
Yours isn't jumping with load though- yours is just jumping off when things get bumpy. It's loose.
One challenge is that if you buy a new (shorter) chain, sometimes the cogs are so stretched that the new chain will jump on the old cogs, and now nothing will work- necessitating a new rear cassette or even front rings- BUT- yours is a 7 speed.
Those things are tanks. The cogs may be fine. The skinnier 10-11-12 speed cassette teeth/chains are much more finicky and prone to getting trashed.
