I have found tiny black bugs in my home. I first noticed them in the bathroom shower/tub. They run in-between grout/silicone crack or jump when I try to kill them.
I found them in my yard, by my water faucet.
Now, in my room, in the window frame cracks.
They are never alone. I am freaking out.
What are they?

Do you have a dog, sounds like fleas. They can jump 2'.

Jumping would indicate fleas, but your sightings are not in the normal places one would expect to see fleas.

How large are they? Fleas seldom if ever reach 2mm in length.

One thing you don't mention is being bitten. Some people are not attractive to fleas(lucky people) but with that many you should be seeing them jump on you and jump off.
