probably yes, but you can tell if you put a chain on it and see how smoothly it runs. if chain can go thru smoothly then you’re fine

Are those aftermarket jockey wheels on an acera derailleur?

I think it’s time to buy a whole new derailleur.

Those wheels very much look like they’ll engage with the chain. You’ll look supercool, but will only roll downhill.

You’re looking at a very small ratio cluster? The chain should pass through, but you won’t have too much range between highest and lowest gear.

Short answer yes
Long answer hell yes.
Jockey wheels are oversized for that derailleur and due to them being considered wear items best practice is only ever replace plastic with plastic. They are plastic to prevent excessive chain wear, excessive chain wear prematurely wears the cassette and chainrings which get expensive to replace.
On a side note the last time I checked the Tourney derailleur was considered non serviceable by Shimano. It’s their cheapest offering and not due to that and the quality coming from its price point not economically viable for them to provide parts backup. You would be better advised to spend your money on upgrading it to a better model that will improve shifting performance rather than on sparkly jockey wheels that will cause the rest of your drive train to fail earlier.
