Unfortunately if you can't even press spacebar with the other hand and are serious about only being able to use the mouse you'll find yourself locked into a much reduced selection of the usual games library.

I hope for your sake you have at least a mouse with some additional programmable buttons and not just the $10 budget one with two buttons and a wheel.

In terms of stuff I know can be played at least to a degree mouse only:
The old original Audiosurf. Mono mode game play which is all about avoiding hitting things is very easily done with only the mouse. Basically turns music into maps to play through.
Bloons TD6, a tower defense game. Usually you'd trigger powers using keyboard shortcuts but they can be clicked on via mouse less efficiently.
Various 4x games like Civilization 5/6, Endless Space 1/2, Stellaris, etc. Not using keyboard shortcuts makes navigating to various deep menus very time consuming but these games take hours to play through anyways.
XCOM and XCOM 2. You'll probably want binds to rotate map vision more easily but these *should* be fully playable with only a mouse. Beware the RNG though. 99% chance to hit resulting in a miss with a point blank shotgun is a meme from this game for a reason.

Are RTSs out of the question? If not i'd like to reccomend C&C Red Alert 2 Yuri's Revenge, it's both the best and the worst in the series IMO. It puts both the most interesting side of the gameplay sandbox aswell as how laughably bad said sandbox is balanced on full display, while also keeping the game very playable.

I do have use of my left thumb for space bar. Thanks for suggestions

Touch screen could bypass the KB and mouse all together and just use your right hand.

Outside of steam - Sims, Anno 1800 or 1404, Settlers 7...

You could also get a mouse with mapped buttons on the side like the Logitech G600 that would open up ARPGs for you - Titan Quest, Diablo, Torchlight, Grim Dawn, Path of Exile, Adventures of Van Helsing. I did this before it's an OK experience so long as you're not playing competitively just chill at your own pace.
And probably MMOs that don't do WSAD for movement just enough to map your abilities if you had something you play already you might be able to continue with that sort of mouse.

One idea. A multibutton mouse. Like cat said. I use the Logitech 604. I was never able to train my left hand to hit all those different keys. So I put crouch, jump, reload, run, etc on the mouse. I mostly just use the wasd buttons. And the number keys to switch weapons.
A very long time ago, I started out by using the arrow keys. Because I did not know what I should be doing. So I started with multibutton mice as soon as they were available.

Might not be exactly what you're looking for but fully playable with only a mouse

From what i remember this could be playable only with a mouse, might ask in their hub if interested, also it was on sale for 4 euros some days ago.

Just about anything turn based can be played with just a mouse. When I broke my hand several months back I was in a similar situation and discovered that could mostly comfortably play just about every turn based game I had with just 1 hand for the mouse.
