If you just want to try for a few hours, you can add GPU(s) onto a GCP CE instance. Along with the trial credits it should get you a few hours poking around with cuda.

Otherwise, get a pre-owned GTX950 (one that doesn't require external power supply) and a TB3 to PCI-E x16 adapter. Not enclousure, adapter. Should cost you around $200 all in IIRC. And it allows you to upgrade the card furthur down the line since most of the cost is the adapter.

Do you know what exactly I should search for when looking for a "TB3 to PCI-E x16 adapter"? Will this utilize all thunderbolt lanes available? I've got a newer laptop that, I believe, has all lanes available.
