It depends on what you mean by "on Bitcoin"!
Bitcoin protocol and its smart contracts does not have the option to create NFT, DeFi or any other token. So if anybody is claiming they've created a token "on Bitcoin" and are trying to sell it to you, that's a clear case of a scam.
The best example of it is the Ordinals which is the biggest ongoing scam.
However, there are sidechains available that are tied to bitcoin but aren't actually "on Bitcoin" (more like pegged to bitcoin) that have the protocol for more complex smart contracts and allow token creation. They are not scams.
Off the top of my head I can name RootStock (RSK) as an example of such networks.
will be success
I don't think so.
Tokens existed for years in this world and they have not had any kind of meaningful success so far. Their only purpose have always been to raise funds, scam people and/or be used for pump and dumps. They have served no other purpose in the real world. So we can't really imagine any success for them in the future either, regardless of where they are built.
